I was given one as a birthday present almost two years ago. The temp is interesting but tiny. The ETA appears to go by what you last did (i.e. if I go in and press reset is uses 16.2 miles as the target distance). I was also hoping the back lit would be easier, mine appears to reset to a default that requires you to hold the back and press down while riding in order to turn it on for a one touch light. Very annoying. The time (my actual need for a computer) is tiny and I rely on it to tell if I'm on track to get to work on time. I haven't bothered to figure out the collected data. Not strongly recommended.
