I have one. I like it. The buttons appear to be flaky once-in-a-while.

The tenths-of-a-mile digit in the distance number needs to be bigger and the speed number doesn't need to be quite as big.

It's too bad it doesn't indicate whether you are faster or slower than the average speed (it looks like there was an intent to do that because there are "unlit" triangles under the tenths digit of the speed.

The battery consumption seems decent (I have about 600 miles on mine).

I like the dual Bontrager sensor. The rubber band attachment can be a bit of a pain to put on (when the rear wheel is installed). Once on, it appears to stay put (I was worried that it might come loose). The sensor has LED's that indicate that it is aligned with the magnets (each lights for 10 counts of its associated sensor).

The computer is expensive but note that it includes a heart rate monitor (I managed to get the sensor free as part of the sale).
