FM transmitter/charger?

[FoFa]

Soundfly BT Ultimate Bluetooth Car Fm Transmitter WMA/MP3 Player for SD Card, USB Stick, iPhone 3Gs

It has a great sound with no static. I love it. I just put the droid in the motorola window/dash mount and plug in the charger if needed. It also comes with a microphone so your calls can go through your car speakers.:icon_ banana:
Woof~

I have seen some bad reviews and mediocre reviews about this one.
