Cons: This thing drops the bluetooth connection with my phone (htc Evo 4G) on about 1 out of every 3 calls. In the middle of a call, the speakerphone will just drop out, but the call stays connected. I've stopped using it since it is so unreliable. All other bluetooth devices work perfectly.
Summary: I am using this speakerphone from the last two months. Here is what I think. Pros: 1. Battery life is good. 2. I love the FM transmitter feature. As an earlier review said, it does induce a little static at times. But that's negligible. My TV has FM reception. So I use this gadget to play music from my phone on my TV. 3. Wow factor. It definitely evokes a wow from your gadget freak friends.
