I have one. I like it, but there are drawbacks. First and foremost---it is a PITA to set. The setting procedure is series of holding and pressing(two separate acts) tiny buttons on the back of the computer, and if you screw up a step you have to start all over again. Also, it is a pain to see your total mileage. On computers I've had in the past, I could scroll through settings with the computer mounted to the bike. I could see trip distance and total distance easily. On the Cateye Commuter, you have to take the computer off the bike, push a tiny button on the back(better use a pen for that), then scroll through day/week/month/then total. It's a pain, and overly complicated.

The computer itself is fine. The screen displays a lot of data at once, and you can click through a few settings to display what you want. The backlight is nice, also.

I don't even mess with the ETA feature, because it's another series of tiny button pushes.

My next computer is going to be simple. Unfortunately, for Christmas my mom and my brother bought me Cateye computers. One bike has a Commuter, and one has a Strada Double Wireless. Guess I'm stuck for a while.
