I've had one of these for about 3 years and LOVE it! It's perfect and provides a much better sound than Bluetooth. After three years, though, I've had to repair with electrical tape, so I decided to buy a replacement. HOWEVER, the replacement DOES NOT WORK. It's exactly the same brand & model as the one I wanted to replace, so there must just be a defect in the new one. I am bummed. However, the seller has been willing to reconcile the problem.
