Purchased Sept. 5, 2009 from Blue Harbor Online vendor for $26.98. Very easy to set-up. I thought I would experience a lot of interference or fall outs etc, but this economical purchase exceeded my expectations. One button control for pick-up, re-dial, on-off, pairing, volume, voice commands, etc. Just have to remember how many times and how long to hold the function button. It takes a little effort to press the button. All in all, a great investment and great purchase. Has been very reliable so far and construction is sturdy.
