I actually use this more for voice recognition and office dictation via wireless set up then for my phone which is not Bluetooth enabled.The instruction booklet was very informative, however the unit, which I chose because of battery life, does somewhat pull at the ear.The plastic piece that connects the unit to your ear after one week of use has already snapped, and despite crazy glue unfortunately snapped again. The voice recognition part and transmission is excellent and the battery life is as advertised at eight hours after an overnight charge. While sitting in the ear, the buttons are fairly accessible without playing around. I used the Jabra product and the voice clarity on playback was not as good. Now the way this unit looks, you can pretend that you're a Starfleet indications officer, if anyone watched the old series. Overall I think it's performing as expected, and if it just was better able to hang in the ear, I'd call it an excellent unit.
