I have always been pleased with Overstock.com quality, so I was disappointed in this product. The idea is innovative - eye shades that play soothing sounds or music. However, the pair I received didn't work much longer than 5 minutes. Even with fresh batteries, they just don't work any more. As eye shades, they are quite heavy, so you are forced to keep your head in one position. The mechanical parts keep you from sleeping on your side. I still think this product is a great idea and with a little fine tuning could be perfected.
