Like all new gadgets, it took me a short while to figure this thing out, but once I did, WOW! Being on the visor beats the heck out of having something stuck in your ear. You can look up and see who is calling you with the caller ID feature. If you want to answer the call you just touch the unit. You don't do anything to end the call, just let the other end hang up. Nice.
I think it sounds great and everyone says they can hear me fine. When I exit the vehicle I turn the unit off which makes the battery charge last forever. It has a bunch of other cool features, too many to go into now. I have tried several other blue tooth devices and was not happy with them. Try this and I think you'll be satisfied.
