Query: Disappointment

I loved this pedometer until I changed the battery. After that nothing worked. Followed all instructions carefully. Company unresponsive...have to pay to send it in and send it back and no promises about fixing it when you send it in. Used pedometer only for about 7 months when battery needed replacing. Need proof of purchase for any warranty work...but still paying for all shipping and no assurances that it will be a warranty related matter. Does all that make sense for a $22 product? Not ready for primetime piece of equipment.
