Review (4/5): I counted the days I was without it...
My original Sonicare died after about 2 years. My wife spent [...] bucks on it and needless to say I was not happy to see it go. You would think a $[...] toothbrush would last pretty much forever... Anyway, I replaced it with this much cheaper model and am very pleased so far. In addition to being a lot less expensive it has a much simplified design which should last longer, and has a user replaceable battery.
On the negative side, it seems to chew through batteries. In fact I actually reported the first one Amazon shipped as defective as it stopped working after 5 days. Turns out the batteries I swapped were dead too and there was nothing wrong with the toothbrush after all. My bad. The fresh batteries I installed only lasted maybe 3 weeks or so. I'm going to use rechargeables from now on, but just be forewarned that this thing gobbles batteries.
But in terms of the operation of the toothbrush I love it. In the short time I had to use a regular toothbrush waiting for this to arrive I felt like I had trench mouth. No matter how long or how vigorously I would brush my teeth just never felt clean, and by 10AM if felt like I hadn't brushed in days. The commercial is a cliche but it's true - Sonicare makes you feel like you just walked out of the dentist office.
