Do you love your Bluetooth?

I have been looking at Bluetooth speaker phones lately. I am thinking it would be really nice to have one for my cell phone, but my dad got himself a Bluetooth headset about 6 months ago and he hates it. It won't connect for him when he wants it to and sitting in the car, right next to it, it will disconnect for no reason. I am wondering if they need a little more time to work out all the bugs before I look to much further into getting myself one? Does anyone else have any experience with them?
