Query: Dropped once and stopped working

I purchased this pedometer based on another person's review which raved about its durability. It worked great the first day until I leaned over to pick something off the floor at my office. The pedometer popped off my waistband, fell about 2 feet to a carpeted floor, and stopped calculating completely. Needless to say, I was disappointed that the pedometer didn't even make it through the first 24 hours and sent it back. I understand that pedometers should be "motion sensitive", but given the punishing that runners and hikers put them through, they should certainly be able to survive the occasional drop -- especially to a carpeted floor. I do not recommend this product.
