Query: Does what it should

First bluetooth device I've delt with so for experienced users this may not mean much...after all what do I know? Anyway, the set up with the phone was easy, I've had no trouble with hearing conversation, and have had no complaints from those I've called. I'm often around idleing diesel trucks, near traffic and so on and the communication seems to be fine both ways. I do find the "beep" when passing through a dead zone to notify loss and regaining of signal a little bothersome, but that may be normal and I'm new to bluetooth.I've yet to run down the device, so the charge seems to hold up well too. Overall I've been satisfied with the product, performs as advertised and does what it claims.
