Review (1/5): Absolute Garbage
My old Sonicare died after and few years and I had tried using several different brush types, manual and powered, attempting to find a cheap replacement. After a less than stellar annual check-up, I decided to just buy another Sonicare.
I saw this model and could not believe how little it cost. My old one was over a hundred dollars. It worked great too. I saw no difference other than the lack of the quadpacer timer thing. Unfortunately, it died in less than two weeks. And no, it was not the batteries, the thing is just dead.
I suggest you buy a rechargable 4100 for forty or fifty dollars. I have been using one for a few months now with no issues. It has the great cleaning action of a Sonicare at a reasonable price. Same as with the cheap battery powered model, the brush turns off after two minutes but does not have the quadpacer or any other fancy features.
