Side by Side Comparison of: KoalaReef vs Universal Vacuum Bags

These bags are made of substantially thicker plastic than others I've tried They are very large capacity, true to the size advertised, with strong double zip tracks. (I previously left an unsatisfactory review, but please ignore, I got my bags mixed up with those of a different manufacturer. )These bags are comparable to the well known brand bags that we use for sandwiches and things. Top notch! This package especially is so useful to me as I store my summer clothes, saving me much precious space. I feel confident that I can safely store my clothes in my damp basement, that's how thick they are! Thanks KoalaReef!

I have a Dyson vacuum and have been looking for vacuum seal bags for YEARS that would work with it. Anyone that has a Dyson knows that most of these bags don't work with the vac's attachments. These bags do work and they seem to be very durable. I use the round hose novel, place it over the valve and turn it on and it automatically seals a bit to the plastic of the bag and sucks all the air out. This is the storage solution that I've been needing and wanting.

I am writting this review after having my bags for around a month now. I must say that I am very pleased with the bags.My first round of bags were all great, except one had a slow leak in it, that allowed the bag to fill with air within about 10 days. I contacted the company, and they quickly replaced the damaged bag. The replacement set has done very well, and my bags are still as vacuum sealed as they were when I packaged them. Personally, I use these for bedding sets, pillows, and jackets. I store the bags in either rubbermaids, or what I have found works really well, are dry cleaning bags.The dry cleaning bag is thick enough to protect these from any splinters on the floor or anything else that could cause them to puncture.

They have recently changed the product so that it's sturdier. I LOVE it! The package stays sealed much better than any other product I've used and I will definitely order more in the future.

I had an issue with my first set of bags, and only got one use out of some of them. They contacted me immediately, and after they finished developing the new stronger bags they sent me a new batch! This product is wonderful. Im a college student and have very little space in my dorm, these bags are life savers!! Great for storage and amazing for traveling!

Nice and sturdy bags...I used one to pack a king mattress cover inside my suitcase. Originally it would have taken up 80% of the suitcase. Once the air had been sucked out it was reduced to about 40%!!! Once you make sure the seal is tight it will not let air in. Extremely satisfied!

I purchased a Food Saver vacuum sealer last year to vacuum pack and freeze coffee beans so they'd last upwards of the month. I've since been using it for other applications as well, such as freezing leftovers, raw meat and fish. The Food Saver bags were simply too expensive, so I tried these. Over several months, they've worked just as well as the originals. I expected a few holes/punctures, but so far I've had none. No trouble vacuum sealing either, so long as it cut straight edges. I'm still working my way through the first of two rolls, so these have been really cost effective. Highly recommended.

So I have a basic foodsaver vacuum sealer, I got it to try and save money by buying food in bulk when it's on sale or from Sam's Club/Costco. It worked beautifully, actually cutting my food budget in half (I was not being a smart shopper before). However, I was quite dismayed when I saw the pricey foodsaver bags after I finished using the bags which came with the foodsaver. After researching the viability of an alternative bag, I found these. Price alone, it is not even comparable how much better of a deal these are; 100 ft for these vs 30 ft or whatever the largest easily available foodsaver rolls. I'm not going to measure these and be bitter if they turn out to actually be 95 ft - that is a LOT of product for a low price. Again, returning to the anchor of the pricey foodsaver bags, this is an absolute steal!In terms of the quality of the bags, i've sealed up around 30 bags from this roll already (prepping two+ weeks of meals in a weekend), and funnily enough I prefer these to the namebrand bags. I sometimes had a difficult time getting the seal to hold - small gaps in the seal would repeatedly form - and I would end up wasting bags as a result. With these, I haven't had any issues whatsoever; nor have I wasted any bags (yet)! My increasing familiarity with operating the vacuum sealer may be the culprit behind this, but regardless these "off-brand" bags are performing swimmingly.Highly recommend these to anyone with a vacuum sealer (that is compatible with this product of course).

Before buying a Food Saver I read a ton of reviews regarding the different models that were available. In numerous reviews from seasoned food saving veterans I saw recommendations for generic brand, commercial vacuum sealer bag material. It was claimed to be more durable than the Food Saver brand bags, and much cheaper. Once I ran out of the bags that were included with my sealer (which did not take long at all), I bought these.I don't know that they are any better quality than the Food Saver brand bags, but they are at the very least equal...and they are definitely much cheaper. These jumbo rolls are not likely to fit in your food sealer, as they are quite thick. I just put the roll on a paper towel holder and manually roll it into smaller diameter portions that will fit in the included storage area on the machine.Most people buy a food sealer looking to save money by buying their food in bulk and freezing it. I see these bags as an extension of that. You get about a 2:1 ratio of cost to product vs. buying the branded bags, and they work just as well. I will definitely purchase again when necessary, which probably won't be for a while.

Love these! They worked great in my food saver. They were cheaper and had more on the rolls than the name brand. Definitely will buy these again!

This is the first time I've ordered these rolls of bag material and will definitely be ordering more. They work just as well as the Food Saver brand. I've been vacuuming tons of food the past few days and only lost vacuum in one of my bags of sugar but only because I dropped it. Everything is holding up perfectly. Here is a picture of some of the items I've been vacuum packing.

Excellent product, great price and fast shipping !!!!!!!!!!!!! 12 stars Seals food really well, was very happy to buy 2 rolls at such a great price

These r so huge! I fit 5 queen blankets in one. The only thing i found was that it was hard to find a place to store it when i packed it full because u cant fold it at that point. I ended up storing the really big ones under my bed. The plastic feels a little cheap, but withstood a beating from toddlers. Cant tell if it leaks or not yet.

I bought these so I could store my big duvet more easily and it worked beautifully. I recently just took my duvet out because it's colder and used the same bag to store my quilt I had been using and it still worked great. Only thing I didn't like was how the little white piece used to help close the bag doesn't stay on well at all

Solid product. Lesson learned: don't overpack these with things of varying dimensions (t-shirts in one corner, pillows in another). Try to keep the contents of the bag level and it will serve you well. I used 4 bags to transport my closet in the trunk of my car in a 2,600 mile move across the U.S. The only bag that burst open was the one that had hoodies + pillows + t-shirts spread about. The rest of the bags held the vacuum seal really well for 7 days of driving through varying rise in sea level and temperatures, which impressed me.

I really like how convenient these bags are to store items not currently in use. I've saved so much space in my closet! The bads are really big and could get heavy if you overfill. I used them to store clothes and it fit perfectly underneath my bed. It is easy to suck the air out with your home vacuum cleaner. The first bag I filled, I unfortunately grazed it across a medal part of my bed and it slit the plastic right open. That bag had to go in the trash. You have to be very careful with these sensitive bags.I've had my items stored for at least a month now and no air breaches!

This is all would be a storage bag. Though I would not suggest travelling with it. I used it for our suitcases and it was a bit big. Also the clip to close it comes off so can lose it quickly. But if just storing inside the closet then definitely a good buy but a bit pricey for a plastic bag.

I gave these bags only a 4 star rating ONLY because I bought these bags for packing fabric that I need to store as I begin packing for a move. I have never used bags like this before, so did not think through how a bag full of fabric would be heavy when the bag was filled. I simply wanted to be able to store the fabric clean and compact. I think they would work best for large puffy comforters or blankets or puffy coats to reduce storage space rather than lots of fabric or clothing. They are very large and for my purpose for them, the bags will be heavy to carry when I move. However, they are well made and work easily with a little hand vac hose. I have had one on my living room rug for over a week, ready for more fabric and they have kept their seal. With the quality of the construction, I am assuming they will make the move without the seal coming loose. The small bag included in the set I will use in traveling as it seals like a zip lock bag, not a vacuum hose needed. It will work well as a laundry bag on long trips.

Lot of bags cheap, used half a roll has done what I wanted. 4 stars as they don't seem as heavy as name brand but I think they are heavyweight enough for most jobs. For the price I should give 5+ stars but if quality is the grade 4 stars.

I have a food saver and decided to purchase these bags for a lot less money than the original food saver brand.Pros - They seal well as long as you make sure the softer, shiner side is facing upward when sealing.They stay sealed after being in the freezer as long as you seal the bag as stated above.Cons - the rolls are way to big to fit in the food saver but for the cost difference, it's not a deal breaker as you can roll to the right size, cut and store the rest of the roll until needed.Bags do not seal well if sealed with the shiny, softer side down.

This product is a good bargain. 4 stars because the material is thinner than the more expensive products (as expected). This does not come without a cost. While this has no impact to food storage capability or use in Sous Vide, the thinner material is much more difficult to use when inserting and sealing into my vacuum sealer. These bags are twice as likely to be crimped or inserted incorrectly, resulting in some frustration and waste when the bags do not seal correctly.I still gave 4 stars because I have been able to work around the issue now that I know how to work with the product. As a result, the 30% fail rate(3/10) I had at the beginning is back to about the same as the more expensive brands.Here's what I did:Carefully insert them when sealing,Cut the bags with slightly longer margin for sealing and prepTake care not to fold or wrinkle the material during prep and sealing (this is really important!)

This is a great bargain for home users. The only problem is that if you have a home vacuum sealer than you probably can't fit a full roll of this stuff into it. It is an annoyance to have to unwind the roll onto an empty core so you can split it into two less capacious rolls. Still it's a bargain over the FoodSaver stuff so that's a win so far as I care.

Heavier plastic than some of the other products I've tried, although I'm not positive this is quite as thick as the name brand rolls of sealing material. It does work well for sealing a variety of different products; I've used it for things like boneless turkey breast, with seasoning and vegetables, so the flavors meld. You can make a very large bag to create a way to marinate chicken cutlets or similar cuts, and either put the sealed bag in the refrigerator for some time or even freeze it so the marinade flavors the meat as it thaws. I've also used it for cuts of cheese; it's great for keeping mold from forming. The only thing I watch as I'm sealing it is that my food sealer doesn't suck all of the liquid out of meats.

Work with Food Saver vacuum sealer. However, you either have to have the bag perfectly straight or trim a hair off the edge. Either way, they seal great and keep air out of your food. These bags are WAY cheaper than the original Food Saver bags and feel thicker to me. The only issue I've had with them is not getting a good heat seal. However, when I've taken a good pair of scissors and trimmed about 1-2 mm off the outside edge of the roll, I get a perfect seal every time. I have the stainless steel Food Saver vacuum sealer with the accessory attachment. Now, I'm kind of wishing I'd have gotten the one for big game that's even wider than mine.

These are definitely "jumbo," they are as wide as my full size bed. If you're looking for water/insect protection and under bed storage, these will probably suit your needs. However, if you are looking for large, space saving bags, opt for a smaller size as these cannot be hung in a closet or stored in a small space even when lightly packed. That being said, great seller, shipping and I would definitely buy from again. :-)

All of the bags broke. I think I may have overfilled them. Do not put anything hard in them or it will rip them open. I stupidly pot clothes with hangers in them. I'm giving the stars because I think the ripping was my fault but the plastic is also very flimsy and the seams aren't good.

These bags are huge, which I love. But they are fragile. I ripped one at the beginning of use, which wasn't a huge deal considering I had plenty more. I taped up the holes and that seemed to work fine, but I'm sure it will slowly leak air from this point on. The closing mechanism is a bit cheap, and the tab used to seal comes off easily which makes it even easier to lose.

Initially I loved these bags. They're huge! I can fit winter comforter, dome coat, etc. all in one bag. Sealing is easy and the plastic zipper is on the shorter side of the bag.The problem is that after 4 months of use and 2 moves, only 1 out of 4 bags survived. 3 of them developed small tears, which made them useless as vacuum storage bags. The plastic is pretty thin. So treat them gently and they should last.

Editing once more- these bags are okay for short term storage, maybe 3-4 months max. After that each of them began to fill with air again and needed to be vacuumed again. Not a huge deal, but a little bit of an inconvenience.***editing to add, after a couple of months of being stored, one bag started refilling with air and another ripped. Once compressed, they seem to tear more easily. The ones that have held up, have really done their job.These bags are awesome! They hold a ton of stuff and compress nicely. I haven't used the travel size one yet, and one bag did rip, but that was more user error. I would highly recommend them and will definitely buy them again should we need more.

Fairly good product, and yes they are definitely large. After seeing reviews about them tearing easily I took a chance on them and I tried being careful with them but it looks like one of them must have gotten damaged when I was filling it because it started letting in air after two days. They don't really tear easily but I can see it being easy to poke a hole in them if it gets caught on something a little sharp. But, they work good enough for me. They work best for storing under a bed because they are so large. Just don't over fill them and make sure they are sealed. I'm sure there are sturdier bags you can find elsewhere though.

I've ordered these rolls 3 previous times and have been more than pleased. Today, they arrived in a different package than I expected and unfortunately these feel different than what I'm used to. They feel thinner. I haven't used them yet but am about to process 80 lbs of meat and am a little concerned about the level of freezer burn protection these will offer compared to the previous rolls I was getting. When I opened the box, the rolls were skinnier so I knew that they'd be thinner plastic. Not cool

I buy this for my vacuum saver that I have the automatic version. I purchased these because they are far cheaper than getting the original vacuum saver version. Occasionally they do not hold a seal and about 1 out of every 6 bags that I cut I have to cancel before it finishes healing and move the bag around move the food around inside of it and then begin to feel it again because it does not remove the air you can see large air pockets at times. I have even had to throw a few bags away maybe three or four bags per roll. Even with this it is far cheaper than using the original bags. About 90% of the bags were perfectly well and I have food that I can use in my deep freezer for 6 months to 3 years at a time with no worries about freezer burn or oxygen leaking in or anything like that.

I've been testing g the quality of this item. Over the last few days. First off.. If you are sealing anything with ANY bit of fluids it will not seal all the way. That being said I double bagged and sealed it up just fine. With some other items it is hit or miss with what stays sealed 100 percent. . I've done cheeses, vegetables, and cooked left over meats with 100 percent success. I've done deli meats and sauce type left overs with a 50/50 success rate. When I tried them with a me brand bags it was no issue. So for the most part this is a no Brainer when it comes to bang for your buck, but the old saying goes. You get what you pay for and for the price it is a good spare bag to have on hand or if you don't plan on doing any wet type dishes and left overs it's absolutely perfect!

I've ordered and used both this 11" wide roll and the 8" wide roll. I use these with my Foodsaver vacuum sealer. The 50' length of these rolls make the diameter of a full roll too large to fit in the Foodsaver unit, but the lower cost makes this acceptable. Either re-roll onto an empty tube using a shorter length so that they can fit, or cut the bags by hand.When using for bagging a lot of items, I use a paper cutter to cut the bags and a separate heat sealer to seal the bottom of the bags.The 11" wide bags are made of a different material than the 8" bags that I received. The 11" bags don't have any stretch and holes can form when sealing dry food. The 11" bags also have a lot of wrinkles in them which has caused problems with getting a good vacuum. The 8" bags have stretch, no wrinkles, and seal perfectly every time.

The rolls are too big to fit in my sealer. The promotional add states that they will fit all vacuum sealing machines. These do not fit.Never the less the bags seal better and as all around better than OEM bags thats for. I frozen nearly 100 bags of produce from my garden without a single bad failure. The 3 starts instead of a five is because of the fact they do not fit in my FoodSaver vacuum pack machine. You can get around this by simply cutting the size bag you want by simply laying on the counter and then used the machine to seal and vacuum seal the bag

I tried using these with a FoodSaver V3440 to bag 30# of tuna steaks. I had maybe 30% success rate. The first end after cutting a bag from the roll went great but the next side after opening the bag and loading with meat would have the ends roll into itself and would not lay flat to insert into the slot for auto sealing. I wound up having to go buy the FoodSaver bags which did not have that issue. If you have a clamshell type sealer, you won't have the problem - only those models that the bags need to be stiff and flat as you enter the bag end into a slot for sealing.I wound up upgrading to Weston 1100 Pro and the bags are great with it as it is a clamshell sealer.

It comes unsealed too easily.

I don't usually write reviews the day I get a product but in this case, I just have to. It's awesome. These are high-quality vacuum sealer bags. They have a valve that helps keep air from going back in. The air remover pump is awesome.At first, you pump and it seems like it isn't working...but then it just takes a minute to see it working. I love the bag sizes and fit a king size blanket in a bag, and a comforter in another bag and now my closet has so much more room! We have minimal closet space here so it's perfect!Can't wait to use these on a trip and see how much I can pack into one suitcase!UPDATEUnfortunately by morning one of the bags had lost its vacuum seal and was back to its normal size. I tried to reseal it and redo it but it is still getting air in it somewhere. At that point, I gave up and put it in another bag and sealed it.Then yesterday I was packing away more bags and found that 2 more bags were not sealing correctly and were also getting air in causing them to lose the vacuum seal. So out of 5 bags, I used so far 3 of them are not working properly.

It took me a while to use the bags, but when I did, they didn't work at all. I sealed the necessary areas and vacuumed out the air, but within a day the items were back to their normal size.

Sealed several quilts in bag and placed under bed. A couple days later the seal came undone and I resealed. A couple of days later the same thing occurred. Great idea but doesn't work so well.

I was really hoping these would work out for me, as I was moving out of state, and needed to maximize the room in my car for my belongings. I followed the directions to seal the bags properly, but two bags failed two times. Once before I left for the trip, and then again during my trip. It's not a good thing when vacuum bags fail while you're on the road. All of a sudden it became very hard to fit all my items in my car the next day, when I was trying to put my suitcase back in my car with less space. Great idea, but quality is not there.

Bag started leaking the second I tried to store it under the bed. Cool concept, not a very good product.

This is the second order of these bags I have ordered in a year. The first set worked perfectly. This set however has not been as good. I sealed 6 or 7 things and noticed the other day that these are not holding the vacuum on them. I always put a second seal on each end for extra security. I have not tried the second roll I got with this order. I noticed it when I sealed some dry dog food the other night. It was hard as a rock then the next night I found it had got air in it. This could just be a bad batch so I don't want to say the product is bad. Want to contact the company but can't find the info.

While these are a great buy, the material is quite sturdy. I would say it is nearly as thick as the original FoodSaver bags. Unfortunately, they do not seal as consistently as the FoodSaver brand bags. Nearly every single time I used these, I had to wrinkle the opening where the air is removed before closing the lid on the FoodSaver. While it didn't look pretty, this would allow the bags to still be vacuumed. I probably won't buy these again.

We thought we were getting a deal on these, but only got 50% of the bags to seal correctly. (And those took quite a bit of working with to get them to seal.) We believed we may not have been using them correctly and just decided to keep trying...surprise, they can't be returned after 1 month. So we got to make about 5 bags, and then went out and bought the Food Saver brand bags..problem solved, but money now lost. No statement up front about return window. Bad product as far as we're concerned.

These are the not the same as the 8x50' bags I received. I've been using the former for a while now and just now got to these and they are not of the same quality. First of all, they are much thinner than the name brand and the 8" version. This is a problem because it is not rigid enough to not wrinkle in the sealer which causes a bad seal.Secondly, I believe the thinness of the bag is causing vac issues. I can go back and forth between the 8" and this 11" and I will not get a vacuum half of the time on the 11" bags. This may also be because the waves stamped into the bag are very lightly done. I think it causes a false vacuum without letting air past where the bag touches itself near the seal.I'll give it two stars because I can sometimes achieve a seal on my gamesaver. It won't get the other 3 because its very annoying to use. I won't be purchasing it again

I hesitated to review this product until I could use it regularly. Some how, a tiny slit was cut into the side of these rolls all the way into the bag. I didn't notice it at first and couldn't understand why my bags weren't sealing. Since it is so long since I purchased them, I doubt I could return them. Unfortunately I am going to have to search for that slit every time I want to use the roll and cut my bag from there - whether I needed that much, or whether it isn't long enough. So much for trying to use a cheaper product. Food Saver brand for me from now on.

I will hand it to the seller, they did a great job of getting the bags to my house very fast!I have tried to use these bags to package about 10 different cuts of meats and let's just say every time it has been met with frustration. These bags are actually 11.5" wide, the 11" is the inside width. This means that it DOES NOT fit in a foodsaver 4980 (The model you find at Costco). They are too wide to fit in the built in cutter by about an 1/8th of an inch. Now this is not a big deal...the big deal comes when you try and seal something. If you try and shove the full 11.5" wide bag into a foodsaver 4980 it will not fit. You will have to cram it in there in order to even come close to getting it in the slot. By cramming it in that means you are putting wrinkles into the bag and good luck making a good seal now. I finnaly got them to fit by trimming about an 1/8" off of each side of the bag. That means that each time I want to seal a bag I have to trim 1/8" off of each side of each bag I want to make.But that is not where it ends! These bags just suck! Even when I make a perfectly straight cut on the bag the bags tend to cup inwards which also means that getting the bag into the sealer is damn near impossible. There are also permanent creases in these bags that also make it damn near impossible to create a good vacuum. If I unroll a roll of these you can see all sort of creases in the plastic that just interfere with the sealing process.I guess I should post some pictures of the crappy bags I got but that is way to much effort, i'm just returning this crap.And to justify my 2 star rating here it is.Pros:When they work they work great.They are heavy enough duty for what they areShipping was quick and a head of scheduleCons:They are a pain in the butt to useThey caused me want to use way to many bad words in this review!Don't buy these damn thingsDo not fit in my foodsaver since they are 11.5" wide

We bought these in August of 2015. We needed to store a bunch of RV blankets, towels, sheets, pillows and such. These were all loaded, vacuumed and stored in our fully finished basement where the humidity and temperature are constant. These bags all gave way and eventually leaked. They either split and or basically fell apart. I guess the plastic used to make the bags is short-term and not meant for long-time storage? In any event, I am buying replacements today on Amazon and I'm hoping that they will last longer than these did. I am only giving them a one star because I actually bought another brand on the very same day and while they are smaller bags, they still perform flawlessly. I guess they were made for longer storage needs and with better plastic properties?

They don't stay sealed that great. The clips don't stay on the seal, and eventually they are useless. won't buy them again.

Update- I packed my summer clothes in these and none of the three I used have held their seal after a few hours. I tried to reseal them again a couple of times with same results. Boo, will try another brand :(I've used several brands of these bags, and these are by far, the best. Just this weekend, I took out my summer clothes, and the bags were as sealed as they were back in November when I packed them. The winter clothes and sweaters have gone in, and I'm reasonably confident they'll be sealed as well when I pull them out of the basement in November! Only complaint is the size -they're really big. Too big to fit in a giant Rubbermaid container, like I used to do with a few of the other brands' smaller bags. However, because they remained sealed, not a big deal to just put them in storage, as is.

We have tried to make this work, but to no avail. No matter what it will deflate. Nothing more than a cheap gimmick. Might work if it had multiple interlocking zips...but who knows. Just avoid.

So initially I thought these were awesome. Filled it up, slide the bar across and turned the knob to close it or so I thought. Put it away in the closet, come back to see it back to the regular size. I do recall hearing a little hissing sound from the bottom corner and thought oh maybe it had a small hole in it. That being me to today. I removed all thitems and use a second bag. Same process. Ensured the top was secure turned and turned and turned to get it closed. Comeback to day and it looks as if I did nothing to it. These were a waste. Sucks because I saw a lady buying all the ziplock bag ones on clearance in Target thinking mine were just as good if not better. Guess I should have bought ziploc to start.

The seal is a pain to get right and when I did, the bags tore when I tried to store them. I loved the size but what's the point when you can't even use them? I had much better luck with Ziploc and Magicbag vacuum bags.

I use a Food Saver brand machine. Those branded bags work great! They make and hold a good tight seal like they're supposed to.These bags seem to get a good vacuum initially and seal but THEY DO NOT HOLD THE VACUUM!!! Every single thing I've packed from dry goods to wet goods has lost the vacuum which of course, renders them useless. No more for me!!

Had to return. This is the second order and they were not made as well. You must have one side, textured and one side smooth in order to get all the air out. This package, there was little to no texture so they didn't work at all. I had to go back to the expensive name brand. I'll try again in a few months. I must say that the product was bad but the customer service was VERY good, They took back the product and gave me a full refund.

My first order worked well but this, my second order was total garbage. I could not get them to completely vacuum the air from the bags in most cases and when they did they would loose the seal in a short period of time. I tossed one complete roll and a half of another and purchased the "Out Of Air" brand. Out of Air is a new brand and they are awesome. They work as good or better that the FoodSaver brands. Don't buy these!

This the 2nd time I've bought these bags, the first ones worked fine These will not vacuam. At first I was worried that it was my food saver, then I found some of the first bags I bought and they worked fine. It'll cost me more in shipping than its worth to send these back. I just hate to order more not knowing if I'm getting the same thing.

Finally just about out of my last batch of food saver bags and tried these for the first time today. They are no good, My food saver won't suck the air out of them. I tried several times to no avail, tried an actual food saver bag with no problem then back to these, still no good. Not a bargain if they don't work.

We initially purchased this product about 2 years ago. It was great. They worked really well the first time. This time we ordered 2 packages, that's 4 rolls. Not one of the 4 bags worked with my Professional Cabelas unit. So I thought to my self, my unit must be broken, right. I just purchased a brand new unit, Vac Master Pro 380, and no, none of the bags work in my new sealer either. I now have 4 rolls of bags I can not use. Sucks to be me. It's my guess that it was a bad batch of bags, since the first package I got 2 years ago worked so well.
