Query: Worst product ever...

Any slight movement of the device will cause your radio to BURST out very disconcerting STATIC. If you touch the device in any manner, it will make the music stop coming out of one side of your speakers. It has very very BAD STATIC. Its a great idea, but should not be on shelves.DON'T BUY THIS PRODUCT. THERE MAY BE ONES OUT THERE NOT AS SLEEK LOOKING THAT WORK A LOT BETTER.
