Query: didn't work at all!

I purchased this pedometer because I didn't really want to spend much money, but I should have known better. With every step, there was clicking/ticking sounds which drove me nuts so I wouldn't wear it while walking around the office. It also didn't accurately count steps for me. I programed the stride length, per instructions and then tried to test the count. Sometimes 10 steps = 35 and other times only 4 or 5 steps. Plain and simple, it simply didn't work at all. I returned this and spent the extra cash on an Omron which worked beautifully! Was quiet, accurate, and simple to use.
