I have the lifter with the GN 6210. Sometimes, completely randomly, it just doesn't want to work and I have to run back to my phone to answer it. I must sayit has a good range for Bluetooth, better than my Jabra BT250 (which this is supposed to be the same thing as), but it doesn't answer calls on my Sony-Ericsson phone like my Jabra BT250 does, it will oly work when I make calls or transfer sound. It's nice that it works with both though. Don't leave it in your pocket or it can break, far too fragile. It picks up WAY too much background noise and, like the BT250, it completely useless in the wind. The tech support is not much help, when mine fails to work (about once a week) all they do is make me reset it then re-pair it, which works sometimes and not others. I'm sending mine in for a replacement. If I could do it all over, I would get a dedicated headset for my desk phone (NOT from GN) and a good bluetooth headset for my cell phone.
