CAT EYE Velo Wireless Bike Computer, Black

When they say max 27 inches between sensor and computer they mean it

The good-------------Easy to setup-Don't have to deal with wire management-Straight forward to program, just a matter of familiarizing and getting used to setting up the device with the front and rear buttons, accompanied with the instruction manual/map.-Nice clear display of statistics and how fast you're going-Battery seems to last for ages, being a CR2032 batteryThe bad------------No back lighting, so can't really see what's going on if it's dark outside.-Wireless transmitter suffers from EM interference, as I found out when mounting it on my bicycle that has a front wheel dynamo hub. It would register going 65mph even though I'm just spinning the front wheel to test if it works, with 700c selected during the setup process. Tried mounting the transmitter on the rear forks to eliminate possible interference, but the computer no longer would receive any signal unless the magnet is about 1/16" away from contacting the unit, probably received a lemon? Not so much a big deal as it happens from time to time every now and then.Neutral/Unrelated----------------------Just a basic computer, basically comparing apples to oranges when it comes to more advanced units by Garmin or WahooUsually would prefer to stick to the wired Cateye Velo for a sturdier more reliable transmission between magnetic sensor and computer

It does a lot more than I want, and does everything very well. It is highly accurate. The pictures in the setup instructions are misleading about the wheel sensor. In the pictures, it looks like the sensor has to be parallel to the magnet. That isn't possible on my bike. In my experience, the only things that matter are having the magnet pass withing the sensor range, and have the correct clearance. Overall, a great product at a good price.

Been using it for a while defiantly very accurate and easy to install

Overall, you really get the most bang for your buck with this nifty gadget.To start off, I want to point out a major complaint; some people have difficulty understanding the instructions manual. If you've bought any internationally-sold bike products (this, and Continental for example), but most importantly this, you'll see that on the back there's about half a dozen languages, so instead of sending you a small novel, they give you clear pictures; you don't have to be artistically inept to understand them.Second, the installation process is very easy. Bear in mind this is my first bike computer; it only took me about 10 minutes to look at the pictures and install it. A brief run through; install the sensor/ magnet a few inches away from the rim, and make sure the sensor is less than finger width away from the magnet, but not touching. Next, make sure the computer is installed on your stem parallel to the ground (if you have your stem 'slammed', this won't be an issue). Of course this is only for installing, not setting up the computer ~see manual~Aside from these, the whole shebang really bangs. Now I'll sum up the good and bad:Pros:Very cheapVery accurateComputer is easy to remove, take almost anywhereEasy to read/ understand what's shown on-screenVery small, very light (for all the weight weenies)Easy and quick setupCons:Computer is VERY small, can easily be lost if misplacedExtremely hard to see screen at night, requires good amount of light to see anythingZiptie mounting of computer/ sensor is somewhat flimsy, sensor may move if not tight enoughNot bluetooth or ANT+ compatible, only works with given sensor (not much of a con if you ask me)Something I read, though not sure if true, is that electronics like a phone or light may interfere with proper performance, will update on that laterThings to keep in mind:I just received this today (01/07/21) so I may have missed some things, will update after putting in some miles. Also, the computer may be placed on a compatible strap or mount, so that's another thing. Another important thing is the screen not having a back light, which is a big issue for night riding, especially in dark areas. Something I wouldn't per se recommend, but would do if you're willy and very, very confident, is to apply super glue between the sensor and it's mount; again I would only recommend if you're REALLY confident in the placement of your sensor (may require parental supervision).All in all, if you're looking for a good beginner bike computer at a competitive price, you landed in the right place. Though it may have one or two flaws, they can be completely worked around.
