The basics of this unit are great. More info, less button pushing and simple design. The bad parts are that the construction is not quite as solid or stable as I would like. The cable it comes with is burley & thick, which is nice, the construction is decent, but it cannot handle rough use. Every time mine fell to the ground it went blank and I has to reset everything. Turns out, the battery clips inside were too lose and the battery was moving. I bent the clips to really pinch the battery and that seems to fix the problem. Also, it resets the trip meter and such very easily, as others have noted. If you push it to scroll through the screens and hold it just a little too long, it resets everything. Also, in my pocket I often pull it out to find it reset. 3 stars

This add so much to my rides. It is fun to try to best your time and average speed!
The computer itself is barebones and simple to use. It is durable and just works well! The price is reasonable and I recommend it highly! 5 stars

This computer has so many functions and is easy to use even while riding. No problems with installation and directions were easy to follow. Easy to read screen! Definately a great buy for the price 5 stars

I bought one and it worked well while it lasted. After two years the thing seems to be broken, and frequently resets on me for no apparent reason. I used it heavily and had exposed it to rain but if you buy one it may only last two years. 2 stars

I just purchased another for my new bike. Problem free, easy to use, easy to install and very accurate. For the price, I could only be happier if it helped my peddle up the hills! :) 5 stars
