works great. fits well. I wear glasses, which was an original concern but all is well. Lightweight and comfortable. I can easily switch between r/l ears. It looks like it would be bulky, but it certainly doesn't feel that way. Haven't tried connecting with my mobile yet, just computer softphone. I can answer my softphone calls from the earpiece (which is really awesome!). Even a setting where if its on the charging stand, then I pick it up and place on my ear, it auto-answers the call. Pretty cool.
However, the controller software will occasionally quit/close/die, in a manner where I can't tell/don't notice, thereby severing the connection with my softphone. So, on these occasions, my phone rings, I pick up the earpiece expecting to be able to answer the call... and nothing... That hasn't ticked me off enough to lower my star-rating... yet.
