Side by Side Comparison of: VUPOINT vs SanDisk vs VuPoint Solutions

This scanner works perfectly and is easy to learn to operate.SetupTake a look at the little enclosed instruction book to set it up.I set mine to export as .jpg since I use mostly graphics, but when I need to scan a lot of text, I will change the settings to .pdf so that I can OCR it and have the text in an editable file.ScanningTurn it on by pressing and holding the silver button for two seconds.Place the scanner on the page.Press the silver button once to start scanning.Draw the scanner down the page you wish to scan. If you move too slowly, the green "scanning" light will turn off, and the counter will not have advanced. If that happens, align the scanner on the page again, press the silver button again, then move a little faster down the page.When you have gone down the whole area you wish to scan, stop moving the scanner.Press the silver button to stop scanning. Note that the counter has advanced by 1.Downloading the images:Plug into computer.Download files as if from a thumb drive.I will edit this review when I scan periodicals, to discuss the ease of following the curve while canning from an open book or magazine.

I chose a 5-star rating because I just paid about $40 for a perfectly functional scanner.I recommend it for people who use a Chromebook or lightweight laptop, because you do not need a driver for this scanner. All you need is an microSD slot, SD slot with micro adaptor, or a USB port, and you can access the scanner's memory just like a thumb drive.The scanner has no power cord and does not need a USB cable to work. It is powered with two NOT INCLUDED AA batteries. You also have to buy the SD card separately.The scan quality is very good. I thought that a hand-held scanner's image would be warped or stretched. Not so on my first try: there are rollers on the contact surface of the scanner, which I believe compensate the image for changes in hand speed.

Keep in mind I've only used this product a few times, however my first impression was incredible. I'm an artist so my biggest concern was whether this little handheld wand to stand up to flatbed scanner art expectations. With little to no time, I was scanning and making impressive scans in a very short period of time. I've never been able to scan this quickly with that level of quality.This scanner has surpassed my expectations and is replacing all my conventional scanners that I have at home. the fact it is portable is the super selling point. Easy to move around, light and effective. While the scanner came with a slip sleeve, I recommend getting the carrying case as well. Simply because there are sure to be instances where you'll bump this while in a backpack or briefcase and I perish to think what would happen if I crack or damage the underside.There are two settings for high rez and low rez scanning and even on the low rez it was beyond my expectations. I'm glad I bought this and it will save me countless headaches, times and otherwise cumbersome resources for the foreseeable future.

I have only had this scanner for about two weeks, but I love it! I am crazy about old photographs, especially of my and my husband's relatives. So, I got this handheld scanner so that I could take it with me when we visit older family members and scan all the old pix they have. I was afraid that I would have trouble getting the hang of how fast or slow to move the wand over pictures in order to get a good scan, but, the very first scan I did turned out great! The technique is not at all hard to learn, and there is a light on the top of the wand that tells you if there has been an error and you need to re-scan. Now it won't matter whether the pictures I comes across are stuck in their frames or stuck in an old photo album, I will still be able to scan them! And, most importantly, I will be able to scan all those pictures that an aunt or grandmother my not feel comfortable letting me take home me to scan. It comes with a soft pouch, but I purchased the VuPoint Hard Case for it and that works perfectly. The bottom of the wand, being the actual scanning service, definitely needs protection and I feel better with it in the hard case instead of just the soft pouch.

Despite the negative reviews about this product, I decided to take the plunge and purchase it anyway.I am very far from being disappointed! It turns out the quality of this mini handheld scanner is incredible!I've already tried scanning my school notes, magazine pages, and even the design on a shoe box (I know you are probably like !!?? ) But hey, I was too excited.Bottom line:Pros: Very simplistic setup, as easy as unwrapping a Ferrero rocher ha! The picture quality is close to perfect, given you set it on HIGH resolution. Comes with a choice of Color or BW setting Can pretty much scan anything.Cons: Definitely nothing much, just that you need to be patient, there is a bit of a learning curve. You just have to learn to keep your hand steady and move slowly! It requires a mini SD card, not provided in the package, but one of your old phones probably has one for a start.

Very cool gadget. Does exactly what it should. Use it for magazine articles and book notes to share with others. Must be precise with your hand movement, because once its stored you won't be able to see if it worked until you upload it. Would def recommend

got this to use in my HTC U Ultra, after the card I had from a next brand kept disappearing and coming back. which was totally screwing up my settings.I am having zero problems with this card.

SanDisk holds all my data extremely well and keeps up with my GoPro. I had some photos from a DSLR were lost once, due to another camera reformatting the SD card. SanDisk was very helpful in recovering the data. This is why I am hesitant to switch to the slightly faster Samsung SD cards. No certainty that a company with several device branches would be as attentive...

Great Micro USB card and works great for a handheld gaming system upgrade. I have always trusted San Disk and this was a great price as well. Shipping like always with Amazon was blazing fast. Very happy with this product and it has so many uses that it can be used for. High quality, awesome performance and a great price. You cannot go wrong with this item.

Bought for my Nintendo Switch. So far, so good. You'll need to update your Switch online in order to use and acknowledge this product.

Great card. Works perfectly. I use it in a Voberry® MINI 5Gbps Super Speed USB 3.0+OTG Micro SD/SDXC TF Card Reader Adapter as a backup drive for the important files on my laptop. SanDisk may be a mite more expensive than the cheap Chinese knockoffs but they work!! I have bought three cheap cards recently and none worked and I had to be refunded my money. I'm only buying SanDisk from now on!

I bought this for my Nintendo Switch and it's great. I formatted it using Nintendo's recommended formatting tool and I haven't had any issues w/ it.

Scans pages really fast. At the lowest setting the quality is still good. I can scan each page in less than 2 seconds. Only problem is it still cuts off some of the page near the binding. The scanner head is too far from the edge to reach close to the book binding, I still have to tear apart the book to scan it but other than that it is good quality product.

It was easy to set up and calibrate. I mostly use it to scan receipts, and the scanning process is smooth and quick.I run linux, and it showed up under /dev as soon as I connected it. It acts like a usb storage device, just mount it and copy the images to your PC.However, it seems silly to run on non-rechargable batteries, considering it is something you expect to connect over USB regularly.I'm hoping it consumes little enough power that I don't have to change them ofter.

I have used this to scan news paper clippings, my id card and passport and mostly to scan texts from library books for my studies. This Magic wand does give great quality results that are easy to read and easy to transfer.Why 4 stars- It is tricky at times to know if you got a proper scan as there is no preview LCD. Sometimes I get 3/4 of a page if not properly scanned. This is more of an art to learn how to scan properly. 95% of the time I get what I need. The image blows up nicely to fit reading on a computer screen. I am not sure what the maximum Memory card support is.Batteries do run down rather quickly but I do a fair amount of scanning. One might want to consider investing in rechargeable batteries if you plan on using this scanner often.

So far I like this little scanner. I was looking for something low cost, simple to use. My main usage is for scanning documents to a laptop.Overall the scanning can be done so quickly with this device that it's not a big deal if I have to repeat one because I did a poor job moving the scanner over the document.My only negative so far is the instructions that came with the scanner. I didn't get that I had to purchase or already have a microSD card--I thought that was an optional thing if using the USB cable to scan to a computer. (Plus, I had read a few customer feedbacks indicating their computers would not recognize the device, so since my computer wasn't recognizing the device, I was already thinking maybe mine was defective too.)Anyway, when I went to send it back, the seller asked me to contact the manufacturer first for support, and when I went to the website to try and do that, I found the manufacturer had better user instructions on their website, instructions that completely resolved my issue. All I had needed to do was buy a microSD card, put it in the scanner, and not plug in the USB cable to the computer till I was done scanning.Here's the procedure that works for me when scanning (I choose to use the USB port rather than transfer the microSD back and forth from scanner to laptop):1. Make sure good batteries are in the scanner.2. Connect USB cable to scanner but not to the computer yet.3. Make sure MicroSD card is in scanner. (In my case, I bought a new one and I chose to NOT format it.)4. Turn on scanner with button (hold till it's on).5. Push button to scan (once) and observe the scan light is now on.6. Scan document.7. Push button again to stop the scanning.8. Plug other end of USB cable into computer and observe that the computer recognizes the device (sometimes this takes a few seconds).9. That's it -- the scanned files are now under the DCIM folder of the device folder of my laptop.

I got a refurbished one of these to scan documents out of old statute books for legal research. I have five minor issues that keep this from getting 5 stars.First, I was very disappointed that the software the scanner comes with does not work for Mac's. After an hour searching online, I was unable to find a mac-specific driver for the scanner. But I just plugged it into my computer anyway, without installing any software, and it worked. I have a MacBook Pro running OS X 10.6.6. iPhoto (7.1.5) thinks the scanner is a camera and pulls up the scanned images to import. The scanner also mounts like a USB Flash drive--just a removable disc. You can download and delete the stored JPG images manually. You could probably download and delete through iPhoto too; though, I haven't tried.Second, You *do need* a Micro SD card in order to use the scanner. It does not seem to have any built-in memory at all. This is a little annoying, but the cards are pretty cheap. I happened to have one lying around so this was less frustrating to me than it seemed to be for other reviewers.Third, the scanner comes with a leather carrying case. I bought the hard case that Amazon suggests, thinking I needed some kind of storage case to keep it from getting dusty. If you're not going to be abusing it, like by carrying it around in a backpack filled with heavy textbooks, then you shouldn't need the hard-sided case--save yourself the extra $20. For me, the hard case is probably worthwhile because the scanner's plastic casing probably wouldn't appreciate being carted around in a bookbag.Fourth, the scanner has four rollers on the bottom that spin as you scan a page, so that the scanner knows how fast you're going and can piece the page together; however, they don't spin very smoothly. This could be due to my scanner being refurbished. So far I have been able to scan things successfully, even when the "Error" light pops up mid-scan, but the jerky action seems like it could be problematic in the future.Fifth, some of the things I've scanned so far have pretty thin pages and the scanner actually picks up the print on the back side of the page. I might be able to manipulate the image to erase these ghost images, by correcting the contrast or something. I haven't had that problem with traditional scanners before.Overall, this is a light, portable scanner that I can use to scan pages out of old books and keep from having to live at the library all the time. It does what I need it to do. And it works with my Mac, no thanks to VuPoint.

This is a good wand scanner and works as advertised. The battery life is good. The quality of the scans is adequate in both high and low quality settings. However, because there's no way to stabilize the control of the scan as it rolls across the page, the scans are frequently crooked and warped and require re-scanning two or three times.In addition, the tiny wheels have so little traction and are so small, it's difficult to pull the wand in a straight line. It's also very difficult to see or feel whether the wand is starting at the top edge or past it where it gets caught on the edge and snags the paper.For the price, I suppose it's tolerable but I wish I'd purchased a handle pull model.

When it comes to reliability for Micro SD cards, Sandisk is the undisputed best. There is no question about that. Having used Sandisk Micro SD cards for over 7 years, I can attest to their reliability. I've used their 8, 16, 32, 64, and 200gb Micro SD cards over the years, and not one has ever failed on me. Other Micro SD cards I have bought over the years like Samsung and Kingston all have given out on me over time. Sandisk though, are honestly the best you can get when it comes to Micro SD cards. When I saw this 256gb card go on sale on Prime Day, I snagged it without a second thought. Having had it for over a week now, I'll say that this is great as always, and with 256gb worth of storage, I'll never have to worry about running out of space again. If you're in the market for a Micro SD card for your phone, camera, or any other device, look no further. This is the answer to all your problems. Besides the delayed shipping on this item (probably caused by all the shipments they had to make on Prime Day), it's absolutely perfect.

Would I must say I was a little hesitant about buying something from the warehouse with its description of its condition being very good. It was a day late and a big envelope with a smaller envelope inside containing the micro sd and adapter still in its plastic tray. When I put the card in my phone it said it was corrupt and had to format to fix it for use with my phone. Easy fix and plenty of space haven't had any issues with it. If your wanting it right away and don't care about saving a few bucks you can buy it from Walmart and spend about 5 bucks or more. If you don't care about waiting a few days and not having all that cardboard them definitely go this route.

Have had mixed experiences with other sandisk cards purchased off amazon, having one 32 gig class 10 microsd fail to read in both my phone and card readers after around 6 months, fortunately no critical data was lost. This one seems to be solid so far and if it continues to function I will be very pleased. UHS 1 seems to work well achieving nearly 80 mb/s read speeds with a usb 3.0 card reader. Seems to have no issues keeping up with the write rate of 4k videos on my action cam.

No Complaints.. Good spped.. Works great with the Nintendo Switch

Total capacity formatted with exFAT on my Note 4 is 183GB (196,585,417,216 bytes)Tested fine with both Fake Flash Test v1.1.1 and h2testw 1.4 so not fake.Read and Write seemed fine. Writing music files to it was about 15MB per second and the h2testw verify was 75+MB/sec. Other card readers may do better. Now Samsung needs to put an micro SD card slot back into their Note phones or my next phone will be something else. It is pretty hard to go back to 64 or less gb when you are used to have 120+GB worth of storage.

This card tested at 88MB/s read, so it meets its claim. The 4K speeds are fairly slow at 5MB/s and the sequential write is 15.8 MB/s which should suffice for most applications. This will work well for most people's needs.Tests done on a Kingston FCR-HS3 USB 3.0 reader using CrystalDiskMark 3.0.3 x64.Product ID on the package was SDSQUNC-128G-GN6MAUPC was 619659133795

I was not able to use it as I intended. Scanning documents at Forum. They blocked the entrance of this device.

Disappointed when I discovered I needed to purchase a MicroSD card in order to operate it. Copies everything in one pdf file.In order to get individual pages one has to do a lot of copying, cropping, cutting, and pasting. Best for one page, or item scans.

I bought this product four years ago, tested it out once and was happy with it. Then I took it with me on a long distance biking trip in Asia. This was a big mistake, I think, because I forgot that this product has a bulb in it that can not handle strong shock or vibration. After the trip, it could not power on even with freshly charged batteries. Although I am not sure I think the bulb burned out due to the shock of the bicycle trip. There were a lot of pot holes and I felt once from the bike. Because I did not get to use this product a lot and it did work when I tested it out the first time. Also I think it broke due to my own fault, I don't know how to rate this product so I will give it 3 stars. Just remember don't subject this product to strong mechanical stress or heat from the sun or rain.

I purchased this portable scanner because my sister had one. It works great - however - it is difficult to make a perfect scan because to do so you have to slide the scanner wand across whatever you are scanning in a perfect line or the scan will be distorted. After purchasing it I have found that there are other portable scanners on the market that have guides that will prevent distortion. On the good side is that since there is no guide it is easier to scan odd things that wouldn't fit through a guide.I will work great for you and is totally portable, just be aware that your scans may be distorted if not careful.

For what it does, I don't think there is anything out there that does it better, but really that isn't saying too much.I bought this scanner as a substitute for a textbook since it the text book cost over $200, and this thing only cost about $100, after I got the case and Micro SD card. Unfortunately, not only was scanning the pages tedious, but a lot of the times the scanner didn't line up right and the scans were horrible, also there is only about a 1/2 inch on each side of the scanner where it won't scan, but that 1/2 inch bit me in the but to no end. And though it is marked where the scanner will stop, it is just a complete pain working around it when scanning a book or even notebook; especially if they are the more expensive notebooks, like five-star, and have a big ring holding the pages together. Honestly, after 2 chapters of scanning the textbook I bought the thing for, I pretty much gave up and just bought the thing. I didn't feel like returning the product so I kept it around for copying notes from classmates when I miss class or for sending in handwritten homework via e-mail, but honestly these are very rare occasions. On the plus side, you do get better at scanning, and if you are scanning a single document on a flat surface it should work flawless, but this is just rarely the case.So if you don't mind not having the last inch of a page when scanning a notebook or textbook, or if you are just going to use this to scan documents on a flat-surface, then I can recommend this product; otherwise it would be best to steer clear until something less fallible comes along.

The product performs well and is relatively easy to use. You do have to purchase an SD card to store the images (MiniSD). The scanner can be a little wobbly to use while 1 hand is holding down a loose piece of paper in order to get a clear scan. My biggest pet peave? The scanned images are in LARGE JPEG format. It would be a perfect product if it gave the option to scan to PDF (and auto compressed the image to fit in a printable field).On the go, it is a great way to scan just about anything that fits in the field of the beam, and the images can be set to high-res, color or B&W. Functions as an External Flash when connected to USB without the need for drivers.I scan a TON of documents and it is a bit of a drag to have to convert the images to PDF later, but other than that in a pinch it is durably built and VERY portable! I still recommend it. For the price, it should have the PDF option.

Adapter doesn't seem to workSo far as I can tell, the card itself works fine. When I plug my dash cam into my work computer, I can scan through what I've recorded. Today I tried using the adapter that comes with it (Win 10, 64bit, laptop, with an integrated slot for that fits the adapter) and...nothing. It didn't even notice the card was inserted. The drive didn't pop up, no light flash, it didn't even make any noises. I tried moving the switch to different positions, disabling/enabling, deleting/reinstalling, updating the driver, none of that made a difference. Just for the sake of troubleshooting, I'll try it at work (Vista box), but I'm not sure what that will prove, one way or the other, I'd still like to be to use it at home with out having to bring my dashcam in from my car to use as a card reader.

I bought two of these: one for my Android phone, and one for my Kindle. The one in my Kindle has worked perfectly since day one.Pretty sure the other one has something wrong with it. While it is functional, it has *always* loaded extremely slowly in any device I've put it in (because at first I was worried it was my phone). For example, when I first boot my phone up after it dies, it will take almost 10 minutes before anything on this card becomes accessible. Minimum. Sometimes it could take twice that. This isn't usually super annoying, but it is occasionally infuriating.If I format it, and try to use it in my Kindle...same thing. So I think the card is perhaps a bit defective.So one card worked great, the other one is...problematic but functional. It wasn't worth the time to return it though, as I was headed out of town for an extended business trip and needed it right then.

This was a great addition to my Galaxy S7 Edge for taking on vacation. I took photos and videos for over two weeks, and never had to change out for a new card. After a few months, I kept thinking I was forgetful as I couldn't find photos that I had taken. The problem got worse, so I made sure to back up what I had left. I put the card back in my phone and all seemed well. However, every now and then, I noticed that my photos all went to the internal memory and not the SD card. Eventually my phone declared the card to be corrupted. Although it is nice to have such a big SD card, it is also a situation of too many eggs in one basket. I contacted SanDisk & sent them a phone snapshot of the corrupted message. They promptly sent me a return label. In a couple of weeks, they sent me a new card. But now, I'm hesitant to rely on such a big card.

I use a MAC computer and was trying to view a video from the card that I took on my new camera. When I put it in the MAC it could not read the card. It was formatted as FAT32 and I could view it on a pc but not my MAC. After searching around I discovered that 64GB and larger have some sort of different formatting that a MAC cant read. So I had to put it back in the pc and format it again to FAT32 and then my MAC could see it. The only problem is now the disk says it only has 1GB space. I then had to use the MAC to format it to EXFAT and now it is 64GB and everything works. Not sure why they do that but it is a pain.

When I went to use this micro card, there were 21 files already on it, most with MILLIONS of KBs already recorded on it, mostly just blank white or black nothingness, one music file on it, so I guess it was used prior....everyone that saw it was shocked.Works great but I'm wondering why they would send out one that had stuff already recorded on it.

This item came with the purchase a dual dashcam PYLE USA, the sandisk works great, but the dashcam does not work properly and the one page translated instructions are worthless. It was professionally installed and the cameras sometimes turns on and I have to reset. There online PYLEUSA.COM is a copy of non-instructional instructions. Consumers be awear.

I have not been able to scan pictures without streaks!! don't know what the problem is but the reason that I wanted this was so I could scan pictures from other people's homes. It will not work if all I get is streaks!! would love for someone to tell me why I am having this problem.

The reviews were great, hence my purchase. It arrived in great time, packaged nicely. However, when setting it up, it took me more than an hour (that I don't have to work on stuff), and it still wasn't up and running. I went to Office Max and bought the same manufactures portable scanner for 64.00. That is not the wand as I purchased here, but it was up and running first time set up - turnkey. The quality isn't bad either. I hate having to return things to Amazon, and fortunately it's a rare occurrence. However, even with that the rep that assisted me was very professional, understanding and sent my return label immediately. I said it to her, and I'll say it here....Thank you Amazon, the best money I've spent to be a member of something in a long time. Money well spent. Sorry about the scanner folks, can't give it a thumbs up, but the one I did purchase, the VuPoint Magic InstaScan, where you actually place the document through the device is AWESOME!!!!

I'm surprised at all the praise for this product. Based on the reviews, I thought that this was going to be an ideal solution for scanning diagrams and images from antique books. The problem is that this kind of scanner produces a series of tiny lines to create the scanned image, resulting in very poor quality for images scanned from books or documents.

I ordered one of these scanners and what I received was a knock off scanner. I returned it and was promised the correct one. Two days later the same knock off arrived. These were not Vupoint scanners. They were a no name brand out of china. Amazon refunded my money...but buyer be ware.

Worked great at first. Now all of a sudden there is a huge 2" wide black bar all the way down every page. Tried calibrating as the troubleshooting says. This did nothing except make the black bar blacker somehow. Tried new batteries, new sd card, cleaning the inside and outside of the scanner glass. Nothing works.BEWARE of this scanner!!!! I would pay more for a better one if I could turn back the clock.

This wand is hard to use and creates uneven images no matter how hard you try. If you are scanning pictures you will notice the effects less. But if you are scanning anything with words or lines you will definately notice distortions.It reminds me of the early handheld computer scanners which you had to use very carefully.The portability and the ability to use your own memory is a huge bonus, but I wonder if I'd just be better off carrying a light with a similar size and snapping a well lit picture with my smart phone.

Has some performance issues and seems to stutter a bit on video playback. I did not encounter this with my other micro SD cards which are also class 10. It's good enough for storage, but if you're looking for sustained performance (i.e. continuous recording of hd video), you might run into some intermittent issues. Originally bought this for a dashcam, but because of performance issues, ended up just as extended storage for my phone. It did cause the phone to reboot a few times. Verified this by replacing with a known good sdcard and no reboots. After scanning and repairing on this card, the reboots aren't seen often, but once in a blue moon, the system stalls and reboots still.

It either works, or it doesn't work. I've bought these in the past for everything from cell phones, to tablets, to digital cameras.Being a person who is not really a "techie", I can't comment on things like speed.This time, I opened the package and it did not work.Speaking of package.....this package is terrible. You could injure yourself trying to cut it open.

Purchased 3 over the course of 2016, two of them were DOA. Sandisk was outright hostile about replacing them... I should have contacted Amazon, their customer service is usually outstanding, but I've also heard they'll cancel your accounts after a certain number of returns, so I just had my office replace them for me ;) Can't recommend with a 66% failure rate in my purchase hx.

I'm not exactly sure whats wrong, but file transfers to this card start slowing down, or just flat out fail as they go on for long periods of time.This isn't because the card is filled up, this happens when I am just trying to put 4GB of music files onto an empty 64GB card! It will start the transfer at a solid speeds, but after a minute will slow down to 4mb/s.At first I thought this was just my phone, but now that Ive tried it in multiple Micro SD adapters, and USB card readers I have to blame the card.

The memory card works as good as any other without issue, but be very careful on handling it, the reader I had the micro SD card in was a bit too snug, and I had to put additional pressure on it using my fingernail to try to pull the card out and the card snapped in half. Thankfully i didn't lose any important data on it, but just for FYI... be very careful on how you handle this one. Personally I'd advise using the Samsung micro SD cards... they work just as fast and great, with noticeably better build quality.

i bought this for my Samsung Note in September 2015. it worked very well until March 4 2016 when it became unreadable in the middle of the day. All data appears to be lost ( went two months without backup oops). Both phone and computer say blank sd card. phone says cannot mount, Computer cannot recognize it or force format.Not sure if it is from a new update or what but it is completely unrecognizable on devices.I thought it should last more than 5 months.

Couldn't read the cards I fed it, and i read all the reviews of what to do.

Not a high quality item. Didn't roll smoothly on many surfaces and produced sub-par imaging. Returned for credit.

Not even close to the quality that I was hoping for. Went to visit my grandma in a European country and when I tried to scan here photos, nothing came out nice. Everything cam out with stripes on it.... So sad since I don't get to go there so often... Recommendations to new buyers: Try on ALL difference surfaces before you decide to keep it. Not as good as it sounds.

I could not get to work with my computer --I have an apple of course it is 4 years old but it would not sync

Worked well for a couple of months and then suddenly stopped charging or activating. It is a good device if it worked. I tried different cables and usb ports. No joy, a dead machine.

The wand heats up to the point it burns my finger. It turns off automatically after 2 seconds, saying that battery is running out, when it's new battery. I brought it for $80. The worst thing I did was not returning it after the bad testing. I thought it's just that I didn't know how to use it. After two years, and I have more understanding, I realized it's a faul product. The worst buy. Doesn't scan at all, and it heats up.

The SanDisk 128GB micro card arrived today. I inserted into the slot above where the SIM card goes. I get a message saying card is corrupted! I will return this immediately! I've installed SD micro cards on other phones in the past without any issues. Don't waste your time or money. A huge disappointment!! This product doesn't even deserve a one star rating!!!

DO NOT USE WITH GOPRO. bought it for my session 5. turns out this is the old version and the write speed is like 15 mbps this cannot keep up the gopro and will cause it to overheat. it also causes random pauses in the video. i've heard it can cause the gopro to crash when it overheats but i haven't expierienced that yet. instead buy the sandisk extreme or other recommended micro sd card on gopro's website. buy once cry once.

I just can't recommend this to anyone. Yes it's cheap and I guess you get what you paid for? I don't know, however, I did NOT expect it to be this slow. I only use it on my phone so I didn't really think the speed would be an issue. I was wrong. Save photos and videos on it is a pain in the ass, it takes a good 5 seconds after every picture before I can take another one. Just today I was deleting a fairly large file(2.2 gig) from it and it literally took 10 minutes just to delete it...it even said so on the prompt. You also CANNOT format this thing as internal storage because an error will come up saying it's way too slow and does not meet the speed requirements. So yeah, I can't recommend this to anyone...even for people who don't care about speed and just plan to use this on their phones because the slow read/write speeds will actually affect you.

My GoPro said "SD ERROR" and kept shutting down, so took the card out of my GoPro, and put it into SanDisk's adapter, and inserted it into my laptop to try to format it.Suddenly curls of smoke rose from my laptop's SD card port and I smelled burning plastic, so I pulled the card out, and found this. It was super hot, and there's a possibility it might have caught fire if I'd left it in the laptop for longer.The other three work fine in both the GoPro and the Laptop: they haven't melted yet, but now I'm concerned.I've attached a picture of the melted card, because "pics or it didn't happen". Well, it happened, and there's the result.

Are these knock-offs or seconds or something... I ordered 3 32Gig cards. Most Sandisk productshave been good for me, one other problem in the past. Open the first one and my DJI Phantom 3 said it needed formatted so I tried to let it format, failed. Tried formatting on a Win10 PC, failed, tried on my Macbook Pro, failed. I was afraid to even open the other two so I did a refund. Was given a return label but I HAD TO PAY to return, not that big of a deal but still that much more that I'm out for returning a bad product. Then today I get them back where they had been REFUSED?!?!?! What??? I got online and did see the refund went through but why make me pay to return only for them to refuse them? Just out of curiosity I opened the other two and sure enough they would not format either. I believe these are knock-offs or something like that. They look legit but I'm not sure... After I tried to return them I ordered another brand and they worked fine.

This worked alright to begin with - it lasted for about 3 months in my Samsung S5 phone, it's now giving me a bunch of I/O errors:[13013.698861] blk_update_request: I/O error, dev xvdj, sector 130206624[13015.057642] blk_update_request: I/O error, dev xvdj, sector 130206872[13015.057655] Buffer I/O error on dev xvdj1, logical block 16271763, async page read[13043.154555] blk_update_request: I/O error, dev xvdj, sector 131460896[13044.991772] blk_update_request: I/O error, dev xvdj, sector 131460904[13044.991800] Buffer I/O error on dev xvdj1, logical block 16428517, async page read[13046.603935] blk_update_request: I/O error, dev xvdj, sector 131469376[13047.718948] blk_update_request: I/O error, dev xvdj, sector 131469392[13048.804687] blk_update_request: I/O error, dev xvdj, sector 131469384[13048.804702] Buffer I/O error on dev xvdj1, logical block 16429577, async page readCan't return because the "return window has passed". Not happy about this.
