Query: JunkBox

This is the worst purchase I've ever made. The radio didn't tune correctly, the sound was bad (even with CDs).When I tried to get an RMA to have it fixed it took over a month.Now they've had it for over a month and I have heard nothing. When I wrote to request my money back, I got absolutely no response.Save your money and sing to yourself.
