BlueAnt S4 Bluetooth Car Speakerphone Kit [USEN-BAW-S4]
After reviewing many different speakerphones on this site and others, I committed to the BlueAnt S4. I am a difficult person to please and when my expectations are met and exceeded, I think recognition is in order.  Simply stated, this device does all that it's advertised to do.  I have an iPhone 4 and it works perfectly with the phone. If you have voice commands, as the iPhone has, you are truly \\"hands free.\\" Set-up was fool-proof. The device is well constructed and it's trim size allows it to blend in
