I own a protege 9.0 and have mixed feeling about it. There is only one button on the computer, and that can cause problems. First of all, to press the button, you press up on the entire computer. Pressing the button changes the information displayed on the bottom of the computer. It seems like the button starts to stick after a few months of use and if you hold the button too long, it resets the data.

Also the temperature gauge was not very sensitive. It seemed to read in increments of 4 or 5 degrees....I much prefer the cateye computers. I own a protege 9.0 and have mixed feeling about it.
