2 Stars lucky i got a good price on it
I’ve been using this computer for less than a year and one of the buttons is already falling off . The unit’s response time is slower than the old ones I had in the 90’s. I should have bought another Cateye. That one lasted me a good five years on my old GT.

1 Star very disappointed
after 15 miles it has malfunctioned. Even with battery changes, realignment, it fails to record any speed or distance. Poor equipment.

1 Star Sensor did not work
Putting it on my bike was pretty easy but I couldn’t get the sensor to work. No matter how much I spun my wheel or how close I put the sensors together, the computer wouldn’t register anything.

I sent it back and got a wired computer, which works perfectly

4 Stars Simple and easy to use
I run the RT88 on 3 of my bikes, and have done for several years. I like the simplicity and low price. I have had no problems with reliability. Battery life is good. I’ve ridden centuries and large group rides in many locations in northern California and haven’t had any problems with interference. This unit has everything I need, nothing I don’t, it’s cheap, reliable and easy to use.

I use more sophisticated units such as Cateye double and Polar on the indoor trainer when I want lots of data, but for road use, I found the Vetta is ideal.

5 Stars Solid product
This model is easy to use and pretty accurate. I bought this one to replace the same model that I had for six years but I managed to smash it up pretty good on a rock . Even after that it still worked but the screen and mounting bracket were cracked. Not that flashy but for the price you can’t beat it.

3 Stars Vetta Bicycle Computer
Fairly good computer overall. Setup is tricky. Make sure you follow the instructions very carefully. To reset the maintenance timer, you need to go through the whole setup routine each time. Would not recommend to a friend.

5 Stars Nice unit–good value
It works very well and has a nice feature set. Fairly easy to read during the ride, but not that easy to be riding and switching functions. Three functions are displayed at one time, and usually thats enough for me. Most of the cumulative readings and averages I can check after the ride or at lights. Make sure you use one of the two rubber adapters for the handle bars and don’t just strap it on. It will fit, but without the rubber adaptor it will slide up and down a lot. Nice color and comes with a clearish cover if you prefer. Seems to be very accurate, and was easy to install. The directions were complete and understandable. Amazon, as always, rocks.

1 Star don’t get it wet
I already didn’t like this unit. The semi-english instructions sounded like they might be helpful if you already knew what they were trying to tell you. The lapping features were hard to use and didn’t tell me what I wanted to know (as in, how long did that last lap take?). And I had to have the sending unit replaced (thank goodness for the friendship of The Bike Shop). So I was grudgingly getting along with the thing until I rode with it in the rain. Corroded the contacts, and when I made headway getting those back, the buttons failed. Yep, this was my first bike puter. I guess I expected too much of it.

3 Stars Hard to install
Hard to install. Take it to a bike shop and let the professionals do it.
