I've had this bluetooth headset for about 5 months now, and overall I was happy with its performance, but just recently I kept losing my connection with the phone. The problem is a horribly flawed battery cover. It has become worn and will no longer stay closed. When it opens, the battery connection is broken and the device is turned off. I payed about $50 for this unit, and it is now worthless because of a battery compartment design that probably cost less than 5 cents.
