Why all manufacturers don't use the standard universal USB charging adapter is beyond me. If you own a Motorola RAZR or other phone that uses USB charging then you will need another charger for this one. Also the earpiece doesnt fit well on your ear, infact i have had it blow off when I rolled down the window. I recommend going to a store and trying a few on before you buy. Plus the volume and reception is terrible. Any ambient noise and you can't hear your call. I also notice it may still have a charge but once it gets low it loses connection with my phone. So the total 'usage' time is about an hour. My advice, keep looking.
