My must-have accessory, Supertooth, was a wonderful hands-free driving experience. People reported hearing my voice clearly, and I was able to pick up calls without touching my T650.

My experience with Supertooth and the 700p has been frustrating, to say the least. I have to re-pair the devices whenever Supertooth is turned off. And on long drives, the small headphone icon disappears at times.

I was wondering whether anyone uses Supertooth II with better luck. If so, I'd upgrade in a heartbeat.
