Bigbruin.com has published a review on the Nitrox x835 Bluetooth Handsfree Car Kit
After spending some time with the Nitrox x835 Bluetooth handsfree car kit we have somewhat mixed feelings. Overall, the sound quality is decent and the battery life is really good. Its size and simple visor mounting clip make it easy to move from vehicle to vehicle. It is also a lot better than the built-in speaker phone feature on the iPhone.Nitrox x835 Bluetooth Handsfree Car Kit Review
