Query: Poor design, quality, and service

Quality:The first version I bought from best buy would not enter pairing mode. The replacement paired with my blackberry after a few attempts.Service:Customer service at Logitech was less than informed or helpful with the pairing problem.Design:Notice the pictures do not highlight the earpiece. It has a plastic cover that is easily scratched and peeled off the underlying speaker component. If you plan to put the headset in your pocket when not using it, you have to treat it like a fragile piece of jewelry, i.e., wrap it up or put it in a case. Otherwise, the earpiece cover will quickly be damaged and fall off.Returning the second one was difficult since a month had passed when the earpiece cover ripped off. Again, Logitech customer service provided little to no assistance.I highly recommend any brand but Logitech for your next headset. Good luck.
