I purchased my first Voyager 510 two years ago, my second for my wife about 6 months later and just ordered three more as gifts. Definitely the best BT headset I've ever used! Tried two different Motorolas, one OK, until it died (under warranty), second miserable and was returned. The Voyager 510 just works. People aren't aware that I'm on it, my wife seldom uses her phone without it and definitely not when she initiates a call that's expected to last more than a couple of minutes. Current pricing is great also.Only con I see is; yes, the power switch could be more user friendly.
