Was sold a defective device. It would not charge and would only stay on while plugged into the wall for a few minutes at a time. Requested a refund. The seller sent me a prepaid shipping lable. When I asked about my refund I was asked to provide the tracking. They should have it since they created the shipping lable. I will be contacting my credit card company to report fraud charges. I have reported the seller to Amazon. I refuse to be given a run around about getting a refund of my hard earned money. Would give 0 stars if I could.
