Query: Not very good

I've using the Motorola HS820 bluetooth headset for over a month now. I must say that it is far from the best in the market. It is firstly not very comfortable on your year neither is too light. It was designed only for the right ear, so say u've been talking for long using ur right ear and u wanna shift it to ur left, u can't! The most disappointing feature in the phone is the clarity which very very bad.. What the other person says seems unclear and incoherent. I got this product free with my purchase of the phone but if you otherwise wanna purchase the product, i recommend u don't.
