OK, but not as powerful as an Elite
I lost my Sonicare Elite and bought the Xtreme as a replacement. It does a pretty good job, but is not as powerful or effective as the Elite model. The AA batteries fade pretty quickly, and don't effectively brush your teeth near the end of their lives. I went in for a check-up, and my hygienist noticed the difference. The rechargeable battery models are more expensive, but you get what you pay for.
