I have been using a pedometer for a few months now to try to reach 10,000 steps a day. I have bought several brands and tested them while counting my steps. In general, this pedometer have been the most accurate one I've tried. I have bought several packs of these, a couple to replace ones I lost and a few to give to relatives to track their steps. Out of about seven pedometers bought over a few month period, six worked great and one was defective. The defective one only tracked about a third of my actual steps. However, overall for the price I have been pleased with this brand compared to the other brands I've tried and am not too concerned about the one dud. If it hadn't been for the one defective pedometer, I would have given the product five stars.
