My husband had one of these for years and loved it. It eventually fell apart, so I decided to buy him a new one. Well after a couple of weeks the transmitter stopped working, as in it wouldn't play music on the left side of his speakers. Unfortunately, we didn't discover the product was defective until after their 30 day return policy. After contacting the buyer, they refused to even exchange the product, even though they had sent a defective one. We're really sad, since my husband really liked this product originally, but this was not a great experience with the seller.
