Use it from Sept, 2016. Currently, over 1000 miles on odometer and no complains. Excelent water resistance, found myself under pouring rain on numerous occasions. I do recommend this computer. Still, you have to know, if you want to update the clock, you'll have to reset the computer and loose your odometer data. Now, it is 3 minutes behind.

Works great. Instructions weren't that great on installation, but I managed to figure it out. Very accurate, good size. Large enough to read easily even for my 63 year old eyes, yet unobtrusive. I like it a lot.

This computer replaced an old wireless Nashbar computer. This is larger and brighter than by previous one and has all the basic functions I need. I'm a bit of a retro grouch so I don't need all those functions that the so called "serious" bikers use. I did buy the Velochampion handlebar mount to get it a little higher and out front. Both have served me well so far. I had my old computer for over 10 years and hope this lasts as long.

I had my doubts about this based on the price. Would it be accurate? Would it last more than a few rides? Would it be easy to set up? The answers are: pretty much, yep, and sorta.Accuracy: It seems to come in pretty close to my GPS tracker app on a 20 mile ride. Of course, any inaccuracy would be magnified over greater distance, and I can't really vouch for the GPS' accuracy, so pretty much accurate in my opinion.Durability: After several hundred miles on two different bikes, it still works! I even got stuck in a serious drenching rain and it continued working. Riding in that kind of rain really sucks so I don't recommend it...but at least I knew how fast and how far I went.Ease of Set-up: Fairly intuitive for most things, but after several months now I can't seem to get the clock to accept any input. If you really want to use the clock feature, you can reset it at midnight and you'll be good to go. Otherwise, just ignore the clock. I also don't really get some of the other functions like average and CO2 emissions. I don't care about those other functions, but not having a basic workable clock is annoying. Not annoying enough to lose a star, though, because I can tell the time by looking at my fitness-tracking watch or on my phone.Recently, about halfway through a ride, it quit working. I was seriously bummed! I felt sort of like I lost an important part of my riding experience (though not, of course, the most important). It turns out I had just knocked the sensor a bit when I had locked up my bicycle. Totally my fault. I was really happy to have my speedometer and odometer back!Overall, this CatEye bicycle computer is good deal and I'm really happy with it!

Instructions are printed very small. But once you break out the magnifying glass (NOT KIDDING) they are complete and easy to follow. Bought for my fixie and didn't want a lot of wires or big screen cluttering the looks. This is great, hardly notice it. And the screen is big enough for even old eyes to read without glasses.

This bike computer is very well designed. It is relatively big and it is easy to read. It is also simple to use. It provides only the data the casual rider generally needs. I also found it easy to install. It has replaced a smaller wired Cateye I was using. The wireless is a big improvement, as is the larger, easier to read size. Highly recommended and well worth the cost.

This is a fantastic product. It's simple, straightforward, easy to install and use, and has been, in my many years of experience, tremendously reliable. I've got one installed on all of my bicycles, and have been used one every day for at least the last seven years. None of these units have ever wronged me in the slightest. The only thing I've ever had to do is replace the batteries intermittently as per heavier/lighter use of certain bicycles, and reset each one once it hits 10,000 miles on the odometre. They perform as expected: consistently and adequately. In short, they are my go-to cycle computers and they perform as expected.

Simple, easy to use, and a good price. I had to use the out-front bracket mount to resolve a connectivity issue I was having, but would be using the out-front bracket either way. About the only thing I can think of that would improve this product is a backlight since I often ride at night, but that option is available on another model which I knew about.

Setup can be a little confusing at first, but just take your time to figure out what each part is for and you'll figure it out. I wouldn't recommend cutting the remaining fastening strip so you can remove the wireless speedo in the future if needed, but most importantly; retighten if necessaryThe wireless tracker has to be VERY close to the magnet on the wheel. I was skeptical it would rattle out of place after a couple of rides but it hasn't Experience will probably vary depending on how challenging the terrain is.Mine is on a mountain bike I mostly use for commuting and going on leisure rides in neighborhoods

This product I was very skeptical about it at first because of all the reviews about the connection. But for me I took it on a 20 mile ride and I had no problem. I used youtube to set it up and it was really easy to set up. The readings are very accurate and very easy to use as well. It is also very stylish and if you want to take ur bike riding to the next level, this the key to be able to motivate you and push you to the next level because it will tell you the distance, how fast, and the time as well.

Bike came with wireless a.n.t. system, got the high end rechargeable computer, end up selling it. To complicated.This wireless system is the bomb if all you need is ride time, miles, average. It's all I needed and I love it.Sometimes enjoying the ride instead of documenting the ride is more enjoyable. I just want to hop on my bike and go, without starting an app, or fiddling with a complicated computer system.Thanks cat eye !

This is a very nice cyclometer. CatEye is a good brand, but this particular model has a problem. My unit will spontaneously change its mode and when I am in the distance mode, it has spontaneously zeroed itself without my touching it. Other than these unfortunate characteristics, I like the unit.After realizing that I put the display too close to my hand and it would brush against the display without my knowing it. I moved the display closer to the middle of the handle bars and I have not had any problem since then. Now the operation has been flawless.

This thing works perfectly for me. I put 1400 miles onto it before I took a break from biking. It held up during that time. My only problem with it is the battery eventually died and when you swap out the battery you lose all of your data. So there goes my Max speed and my overall odometer. But it does work well when the battery is alive.

UPDATE: After placing the sensor on the front wheel the computer worked fine, it doesn't say it in the instructions but it does say that sensor and computer must be placed within 75 cm distance, which in practice rules out the rear wheel for most regular size bikes.Unfortunately the computer worked only for a few minutes, I even took it to a professional bike shop to make sure it wasn't an installation issue and they couldn't get it to work either, I've purchased this brand before without any problems but it wasn't the case with this one. Delivery was good, as advertised.

Great computer, easy to set up and install, easy to read and use while cycling. Be sure to set up the computer with tire size, etc., before installing on the bike. Maintaining the maximum allowed distance between sensor and magnet, and sensor and computer can be challenging, but my computer worked fine with maximum distances exceeded. My front fork includes shock absorbers which results in a large distance between the sensor and magnet, thus requiring the sensor to be significantly turned in toward the wheel spokes. Only gave this four stars because the instructions are definitely as bad as previous reviewers have noted. Go to the CatEye website and watch the installation videos first. Then the provided instructions make sense.

After about one month the sender unit was working intermittently and then stopped working completely. I determined that the handle bar receiver was fine by checking it against a sender on another bike. I put a new battery in the sender and got a brief signal, but then it stopped sending within a few seconds. I moved the magnet within a millimeter of the sender and still no signal received. A previous unit has worked fine for over one year. There is a quality control problem at CatEye. Beware because there are no returns after 30 days.I revised this review from one star to four because CatEye sent me a new sensor unit in less than a week. There was a simple online form to fill out at the CatEye website and they responded immediately by sending me the replacement free of charge.

I really like this trip computer and the wireless aspect is really nice. It's easy to reset at the end or beginning of any trip. It pauses automatically when you stop. I've put over 1200 miles on my bike in 20-30 mile increments with this computer and have had no problems. Well, one odd problem I've experienced (thus the 4 stars) is that the CatEye headlight I purchased interferes with the trip computer wireless signal when the headlight is in the blinking mode. That's too bad because the blinking headlight mode is great. When it's dark, I don't really need to see the computer, but I like it to record every mile I out on. With the headlight in blinking mode, the trip computer behaves as if you've stopped.

I'm not really sure if I have this set up properly. I use Ride With GPS to map my rides and always get from half of a mile to 3/4 of a mile variance from the CatEye and that's only over a 13-15 mile ride. That's 4-6% variance. So, it makes me wonder if it's the computer, Ride with GPS, or just user error.(Update: The more I ride the more accurate it seems to be. Lately on 20+ mile rides it corresponds with Ride With GPS to within 2%-3% difference. I think that's pretty good.)

I have used this for several months. I like the size of the screen, as it is easy to read while I am riding. Just a little push and the screen toggles to the different readings. This has really helped to keep me on goal of riding so many miles per day because we take different routes in our rides. It has been a handy tool. I check it with my workout map to see if they are similar. The readings are a little off, but I would think the map would be a little less accurate than this as this is tracking with tire rotations. Now my husband wants one.

Works great, this was my first computer I've ever used and of course i have already went OTB and damaged the screen but it survived! My only complaint was the instructions said it had to be within 5mm of the sensor when in reality it was more like .5mm at best. It literally almost has to be touching for it to register. other than that, it comes with a good mount and is pretty accurate.

Replaced 16 year old nonfunctional Sigma BC 800 as plastic unit mounted on fork had cracked. This is my first wireless bicycle computer and after reading reviews purchased this unit for my RANS rocket. Instructions were good until I got to the section about mounting the fork mounted sender unit. VERY sensitive to 5 mm distance between magnet and sending unit. Initially would NOT work... After adding a small round flat neodymium magnet to the Cateye magnet my problem was solved. I feel instructions about mounting the sending unit could definitely be improved upon and perhaps a stranger magnet could be included in the package.

The product works advertised. Gave it a run against my smartphone and it's pretty much spot on. At first I didn't see the need but when you out riding you need the computer rather that a phone because it gives you information at a glance. I use my smartphone to collect more granular ride data.My only disappointment was getting this through Amazon Warehouse deals. While I saved money initially, I in reality didn't save a dime. The product came without the nylon tie straps and the English instructions. Even though it was advertised as complete and just repackaged it was obviously a used return which is deceptive. I decided to not return the item because it would have cost me even more in time, travel and waiting. I picked up the straps from the store and got the instructions online. I broke even at best. Beware.

A sturdy, very good quality product. Enjoyed using it.Wanted to share some gotchas though1) When I started using this product with Garmin heart-rate monitor to transmit data to my smartphone, it appeared to me that they have some interference with each other. It was not consistent. Heart rate monitor sometimes reported much higher value than should be. Also, Cateye a few times wasn't showing up speed measurements (was reported as zero). I also was using Wahoo strade sensor at the same time. Both strade sensor and heart rate monitor are using ANT+ wireless protocol. Not sure what protocol and frequency Eyecat product is using... but it appeared to me that this Cateye Wireless Bike Computer doesn't operate nice with ANT+ products. This wasn't a scientific research probably, ymmv - after a couple of times I put it into my wife's bike.2) A very minor - clock drift is around 15 minutes / 6 months.Other than that, again, it is a great quality product.

This was exactly what I wanted. It was easy to install with the hardest part being trying to figure out how to get into the menu and set the proper options. It was also a little difficult to calibrate the distance according to your tire size. Not hard on the computer, but hard because I did not have a metric measuring tape. I finally used my wife's sewing tape which was metric. You can use the default tire sizes that it offers in the instructions, but I wanted to be accurate, and my measurement came out slightly more than what the instruction sheet said for my tire size.I mounted it right in the middle of the handle bar stem. I have a gray Trek and it disappeared and seemed to become part of the bike which I really liked. The numbers are large enough to read when riding and it is easy to move from one function reading to the other by just pushing on the bottom of the unit.I thought that setting the sensor onto the front wheel fork and lining up the magnet would be difficult, but it was not. Unlike the instructions though, I mounted it on the front part of the front fork instead of the rear part thinking that if it came loose it would fly off and away from the wheel as opposed into the wheel if it was mounted on the back.Overall very good. The only reason I did not give it 5 stars is because there is no GPS function, but I guess for the money I should not really expect one.

I've purchased three of these in the last four monthsCatEye Urban Wireless Bicycle Computer CC-VT220W based on the positive reviews here. Two were purchased at the end of May 2016. One of those two has quit working. Even though I've had it just over two months I went ahead and replaced batteries in computer and sending unit. I also made sure the sending unit was properly aligned with the magnet on the rim. The unit is still not working. I swapped the computer from one bike to the other and was able to isolate the problem to the sending unit on the wheel. Unfortunately this was sold buy Amazon so two months is beyond their return deadline. They referred me to CatEye for service. I received a lukewarm and somewhat skeptical response from them. After 15 minutes on the phone they agreed to send me another sending unit. I hope this solves the problem. The other two are working fine. I will update when I get the new sending unit and I install it.

Works good but I don't think anyone who wrote the code for the software EVER tried it out. It's truly bad. The issues are, the instructions are horrid, the programming is convoluted, if you have to change anything it wipes out EVERYTHING, replace the battery it wipes out EVERYTHING. So if you have to adjust the wheel circumference to make it accurate write it down. I'm debating on returning it as at every battery replacement I will curse it.

OK quality for what you pay.. Classically bad Chinese instruction.. The on line quick start instructions are better.. [...]Not happy about the cygolite headlight interfering with this computer functionality.. They should inform buyers of this...I own a Performance 8.0W from the mid 90s that I still use.. Same functions, 1/2 the size and works great. Japanese quality.

The distance between the magnet and sensor needed to be extremely close to each other. I can't make it right for the whole day until watch a related YouTube video. I'm Concerned if the sensor might be too close to break when the bike is running. Already filed the return, but if it works out for the next couple weeks, I might keep it. One of the reason to keep is the little strings to mount are too tight to detach. I can't take it out unless I cut them.

It is somewhat of a hassle to set up as the intructions are poor, but eventually I was able to figure what to push and when to push it on the backside of the device to set it up. Rotating through the various information possibilities is easy...once it is set up. Just push the button. Hopefully the batteries last a long time so I don't have to hassle the device again for a long time. The information appears consistent if not accurate. I have not been able to test the accuracy yet. First I need to find an accurate mile. The timing is reasonably accurate.

It was tough to get to function. I think I am pretty able to install such a device but there seemed to be a discrepency in the written directions and the time needed to hold down the button to set the time. Without that being done the device would not function. Fortunately my neighbor came over and went over the directions and held the button down longer than I had and longer than directed and got it to work. Since then it seems to work great, otherwise I would have given it a higher rating.

When my headlamp is on, this does not function. NiteRider 550 is my lamp.It was a pain to setup - miss one digit and you have to cycle through the entire menu. Ugh.It's smaller than they make it sound. Hard to read on my eyes. No backlight (not a listed feature though)Sensor mount on a blade fork was a bit fugly. I just mounted it on the edge of the blade.But not working when my lamp is on is the reason it went back.

my first time to use a wireless bicycle computer, I had high hope. The first unit is DOA, the sensor doesn't work properly. it pick up the magnet randomly, Amazon is awesome, shipped a replacement upon request. The second unit works fine so far. time will tell

I use this on the rear wheel of my bike since I have my bike on a trainer in my house due to the freezing cold winter. I can keep track of how far I have went on each ride and the total distance I have went since using this device on my bike. It is easy to setup and use, but the biggest problem that I have for this device is how easy it is for the display unit to fall out of the cradle. I am sure that if I was riding on the road that I would have lost it as soon as I hit a bump or was riding downhill. Riding on the trainer in my house it has slowly worked its way loose out of the cradle. If this problem didn't exist, I would easily give it five stars. If you can velcro or glue the display unit to the cradle so you don't have to worry about losing it on the open road, I would highly suggest that you do it.

I have had three of these computers with close to 7,000 miles logged so I know this computer. The ClickTec interface is awesome. With it you can easily switch between modes even with gloves on. The problem with part of this design is in the way the clearing of data is engineered. It takes barely 2 seconds of holding the unit down to clear the ride data. Other reviewers have complained about this. It takes such a short hold on the unit that often ride data get inadvertently cleared when just briefly resting an arm or hand on the unit. To prevent this I leave the unit in trip 2 distance mode. One of my computers crapped out by unknown causes after 3,000 miles. The small button on the mounting base that locks the unit of another also broke. On the plus side, small parts are easily obtained from the company for a pittance.

Overall, this is a pretty decent computer, but the display is very small. The display area is only the size of a postage stamp, and the data on the lower display line is very hard to see. The unit is also very hard to snap out of the bracket, and you need to do that just to update the clock. Cateye also only includes two zip ties for the remote sensor, and they're a hard to find size, so if you need to reposition the sensor you'll need to order new zip ties from Cateye ($4 for 10 ties). I'm sure these cost Cateye a couple of cents a piece, so I don't know why they don't include an extra set with the unit. Position the remote sensor unit carefully before tightening those ties!Those negatives aside, the unit was fairly easy to install, and it's very easy to use. It also looks very sleek mounted on a road bike stem, and the mounting bracket design is flexible enough for mounting on almost any bar or stem. I also found it to be very accurate, and it's nice it comes already set up with the default tire size circumference setting at 700x23, which is the most common road bike tire size.Overall, a decent cycling computer. If it had a larger display and was easier to remove from the bracket, I'd add a star.

I am very happy with this computer. It does the job and nothing more. Easy interface--the whole front is basically a giant button that procedurally cycles thru the modes (no pun intended.). All the basic necessities for a cycle computer are present. The mounting hardware for the sensor needs some improvement, however. I found the sensor's cheap cable-tie mounts to loosen over time, but since part of the installation instructions are to cut off the excess part of the ties, there's not really much way to adjust unless I purchased new ties.

broke after several months

DECEPTIVE Description: Technical details give item dimensions as 2" X 3" X 4.25": 25 cubic inches. That would be about the size of a large box of wooden kitchen matches. The actual device is smaller than a book of paper matches: 1 3/8" X 2" X 1/2": 1.375 cubic inches. That is about 5% of the advertised volume. The display is less than 1" X 1 1/4". The digits are 3/8" and fairly readable at arms length but not what you might call "large".I just received it. Haven't mounted it or tried it. The output might turn out to be everything I ever wanted -- or not.

Unreliable compared to the wired unit I have since purchased. Failed to correctly log speed and distance on occasion. Followed the instructions to the letter.

headlight operation interferes with computer reading. Only works if headlight is in flashing mode. Otherwise when light is on, computer does not pick up signal.

I would go with the Bontrager Trip 100 Computer. You can find it at a Trek store. The Bontrager is a very simple to use device, with great features and a large display.

On my bike it does not receive the signal close to where I can see it. All the functions work well. Now is I could just see what is going on it would be fine.

I'll Start by saying I don't usually write reviews. The exception is when I think the feedback is more valuable than to just say its great or it stinks. I read dozens of reviews on this computer before buying and overall it got good reviews, but there were some complaints about it resetting on its own. I disregarded the complaints as flukes, but should not have. I ordered one of these for myself and one for my daughter for a week long bike ride we were taking covering 400 plus miles over 7 days. The unit my daughter had reset itself almost everyday and sometimes more than once during the day. The one on my bike reset itself once during the entire week. These resets occurred while riding and while the bikes were parked with nobody to touch them so I know that it was not user error. All of the daily stats are what resets. The only stat unaffected was the total mileage on the unit which measures all your miles from the time that you strap it on your bike. I think the only time this resets is when you change the batteries, it can't be manually reset. Anyway beware, chances are you are going to lose data using this computer. It was disappointing especially on my daughters bike as we were trying to keep track of the miles she rode daily and over the week since she did not ride the entire route because of her age. Each reset wiped out any hope of keeping track of that. Once the mileage resets you also lose all of your average speed data. Time riding resets and so does max speed. You lose it all. If this kind of thing is valuable to you don't buy this computer. On the positive side it was easy to install, seemed accurate based on comparisons to other bike computers in our group for distance and speed, it was easy to use while riding, and easy to understand its functions, it looked nice, and was easy to read while riding, and the wireless function worked well. All in all a nice unit, but one I would not recommend or buy again because of its main flaw, the resetting problem and loss of data. I think CatEye has a problem it needs to address. Hope this helps you make an informed decision.

I purchased this Cateye CC-RD300W Strada Wireless computer 30 days ago, and installation and set-up was very simple. The unit works great during my daytime rides, but unfortunately, I was surprised to discover that it does not work when my bike light is turned on (also mounted on my handlebars). I spoke to a customer service rep at Cateye, and she confirmed that most wireless bike computers will "shut down" when in close proximity to a bike light, due to "interference". This would have been nice to know prior to purchasing this computer, as many of my rides are during times when I need my light. Of course, it's not critical to see my "mph" during night rides, but when the computer shuts down, it also disables the ability to track my distance traveled and average speed. The only feature that works when my light is on is the clock.

Installed this on my road bike, and it stopped working after 3 months or so. Tried replacing both batteries, the wheel magnet, and readjusting alignment every which way and still nothing worked. Could have gotten wet inside one of the sensors maybe? Display would come on, but wouldn't sense any wheel spin. Really enjoyed the computer while it was working. I truly get motivated tracking things like total miles, time, average speed, current speed, etc. Hopefully mine was just a fluke, but I'll be trying a different model next time.

Initially I did not want to use a GPS device for tracking my riding, I wanted something simple and low maintenance. At first I thought this thing was great on my first two rides or so out and then I noticed it was dropping huge portions of my rides. It would just freeze and stop tracking my distance and start up again on its own.I was using this on a 26" wheel tried different batteries, multiple locations and angles and every time it would initially seem ok and once I would get on the trail it would start failing on meI now just use a cellphone in a tube bag with Runtastic's bike app and actually enjoy it much more since it automatically uploads so much more data for me to see and share if I like

Pros: It's easy to set up and accurate - most of the time.Cons: Data is often corrupted by interference from sensors at traffic signals. A few other reviewers have mentioned this - I'm surprised not more. Maybe these sensors differ by locality, and I'm just unlucky enough to be in Seattle. I have to be very careful at stoplights not to stop over the sensor area used by the signal to detect whether there is a car waiting so that the light will turn green. Of course it doesn't detect me on my bike, and the light stays red forever, but what it does do is provide some sort of RF pulsation that makes my CatEye computer think I'm riding at freeway speeds. It registers 65.9 mph (the maximum for the computer) and adds distance accordingly, as if I were riding that fast for however long I'm sitting there. That means my max speed is wrong, my trip distance is wrong, my average speed is wrong, my riding time is wrong and my odometer is wrong as a result. This is an obvious source of interference encountered regularly by cyclists, and there should have been an effort to engineer a solution.

This cyclocomputer looses connection with the speed sensor when I had a NiteRider MiNewt 600 turned on to medium and low brightness. In the brightest mode it does not cause interference.I also noticed that at some traffic lights the speedometer registers 65 mph, which basically means that the speed goes off the scale due to interference.Also I had a problem getting the cyclocomputer out of its bracket. The main button would be pressed, and the trip data would be reset.Overall because of the poor reliability of the reading this product is not worth the price or the hassle.

This product is created to fit certain styles/sizes of bikes and no where does it say that. Do they know that? Don't buy this unless you have a large bike, otherwise you will not be able to align the devices in the extremely specific way that is required for them to work. If you aren't sure, it's better to just go with another product and avoid all of the hassle of lost $$ on S & H and taxes.

This does NOT work! I am returning it and buying another product/brand.

Junk....randomly turns on and off while riding. Changing batteries does no good. Adjusting distance between magnet and sensor does no good.

Product worded for a few minutes then when I tried to change it from KPH to MPH it wouldnt let me and the it kept flashing the same screen and it's not even usable. Waste of money...

I liked the product very much and it worked well,then the odometer portion stopped keeping mile totals,every other feature continued to work,I tried contacting Cat Eye but got no response,so....I liked it very much, but have to dislike it because now I need to replace it.

I wrote a review- who knows where it went.I read about the useless instructions before I bought this. Stupid me.Pay Attention, Grasshoppers:1) Take out the battery, put it back, to get to set-up.2) Press the SET button on the bottom(yes, there are 3 buttons on a ONE button device) to confirm your new settings.3) Watch the MODE'S "2 second rule" to get things set smoothly.4) You will learn as you go; if it gets messed up, push the RESET button on the bottom and start all over.5) If you use the bracket, PEEL off the white tape on the little plastic strip.6) It is virtualy inpossible to remove the device from the bracket, so I suggest you throw the bracket in the trash like I did and USE VELCRO. The device will work where ever you stick it on the the stem or handlebar- I tried it and stuck it at an angle on the stem for stability. Mine ended up about 60cm. (2ft.) from the sender.7) NOW it comes off easily and attaches firmly. Works great. (P.S. Now I'll know my carbon footprint, too.)

I tried over and over and over again to get this thing to work and it just wouldn't. I made sure I calibrated it properly and it just would NOT work. I tried to get the magnet sensor as close as possible to the speed sensor and it still would not register any data. I made sure I did everything correctly and took it off and put it back on about 3 times with no luck. I spent almost 2 hours attempting to figure this out and finally just gave up. This has been extremely frustrating. I ordered this about a month ago and just now tried to put it on because the weather is just now getting nice and now I have missed the return window by one day and am stuck having spent money on an item that does not work. If anyone has a way of getting it to work let me know. Otherwise this product is going into the trash can.

The most terrible bike computer I have ever owned. The instructions are mostly pictorially and the illustrations are vague and confusing. But the biggest disappointment is the range within which each part has to operate or it simply does not work. I have a city cruiser bike and the handle bar sits high and the distance required for each component to communicate was greater, even though on the product description it says this product works with all types of bikes. The yet more disappointing feature is the max 5mm range required between the magnet on wheel spokes and the speed sensing unit installed on the fork. This 5mm range is super limited and it did not work with my bike. I bought one from Bontrager and it works sooooo well. No headaches, no hard instructions, and no guess work with 5mm or 70 cm ranges. Save yourself from this terrible product.

I couldn't get it to read consistently, it would line up for awhile but then it'd get slightly moved and would stop reading properly.

Because of a bike tour I wanted to record mileage on, I decided to forgo the return and see if the problem I had was just a fluke. nope. The radio signal from the wheel to the console goes in and out and this thing is completely unreliable. Since I waited past the date for returns, I am stuck with it. I curse this thing. Will never do Cateye again.

This thing has been frustrating from day one. Honestly, I read negative reviews and I think some people are just experiencing user errors. I am pretty confident I am capable of "installing" this. It has not worked at all and it is too late to send it back. I am very dissatisfied with my purchase.

After I installed it it did not work, I installed it correctly and spun the tire but the computer just would not read. I bought this wireless computer because the wired computer that I had, which worked great, its wire would always break no matter what, no matter how many ties I used to secure it, it would always get caught and break. But I do not recommend a wireless computer. On top of it all this computer doesn't even tell you how many calories you burned.
