Excerpt: Had to exchange it once and ended up returning it to the store. Everytime a call came in, it shut my phone completely off. Tried on a different phone and it did the same thing with both of them. Their "Help" line didnt have any idea what was wrong.
Excerpt: I purchased this device from Staples as a Christmas present for my wife. On x-mass day, we un-boxed the product and gave it a good charge. After a few hours, we went to test it out. The phone (Samsung Epic 4g Touch) paired perfectly. However, the FM transmitter functionality was completely non-working. I called the support number, and the support representative dutifully ran down her checklist ... nothing worked. I was told to bring it back to the store for exchange.
