The sound quality on the one i tried was utter wank, and as with all bluetooth products, it's not what you'd call reliable i.e. - if you so much as look at it the wrong way, it'll lose connection

Get a wired handsfree with charge cradle from THB (wires into ISO plug behind dash, routes audio through car speakers, mutes cd/radio when call comes in etc). All the kit that wires into your ICE system is standard throughtout all phone models, it's just the clip on cradles that are different. Which is handy if you change your phone, you just need to pick up a new cradle for peanuts
