TF checked ou tthis handsfree auto kit and reports it offers excellent battery life and very good sound quality.

"Today for review I’ve got what is probably one of the best Bluetooth speakerphones on the market today called the Buddy, it’s from a company called SuperTooth. I’ve red good things about their products, but never had the chance until now to test any out. The Buddy clips to the visor in your car so it’s easy accessible while driving, and it has a one thousand hour standby time with twenty hours of talk time after charging it for only three hours. "
