I use it. No problems so far. Works as advertised.

One thing I don't like about it is that it is difficult to manually set the distance for an upcoming trip in this computer (so that the ETA display and the trip percentage indicator would work properly). It is possible but it requires suffering through a number of rather convoluted steps (one button user interface). Otherwise, it uses the previous trip distance as the distance setting for the next trip. It makes sense (for a commuter), but in many cases I'd like greater flexibility.
