Review on Philips Sonicare HX3631/06 Powerup Battery Toothbrush - Medium Size in Scuba Blue by Candace Hennessy

I've been using Sonicare toothbrushes for 25 years, one battery powered and one rechargeable. After my last one expired last week, I ordered this battery operated one. When brushing, it's like a model airplane landing in my mouth - loud and horrible vibrations. In addition, the handle is so small that it looks like a child's toothbrush. That's nothing short of the quality of two old Sonicare brushes. If the price went down, maybe the quality went down too. I think I'll throw them away and buy another electric toothbrush. What a terrible shame!
