I gotta laugh myself, just to keep from crying. I just bought the danged thing! I measured my steps and it wasn't working out great. So I did 3 miles on the treadmill and kept adjusting for run/walk and finally found the two settings I needed for running/walking...YESTERDAY! Grrrrrrrrrrrr Then I go out for a 3 mile run today and it's gone. So I went BACK out with my bike. I got my exercise in if nothing else. But there's $30 down the drain.
I just bought the Omron one, it is great, not only does it have a belt clip but it has an extra clip so that you don't lose it. I'm sorry to hear that you lost yours.
