I ordered the BlueAnt Supertooth Light(blah blah blah) because the law changed in California to require handsfree phone use in cars. It is super easy to use and to set up. I'm told the sound quality is fine at the other end of the call - sometimes at my end things sound a little garbled (although that may be my cell carrier). My only "complaint" is that the visor clip is fairly narrow (tight) so it doesn't seem to fit well on my visor - my visor isn't terribly fat so this seems like a small flaw. Otherwise I'm very happy with the purchase.
