Query: I dont like it because..

I have owned many many BT devices (about 20) and find this one is not very good. First its very uncomfortable in my ear, second it disconnects all the time for no reason and does not connect automatically to the phone when you power it up. Last but not least..the range is very limited compared to a cheaper Jabra and Motorola BT. Lots of static and scratching noises when I'm only a few feet away from my Z3, Pebl or Razr. I will return it for another one and hopefully that one will work better...
