For anyone looking for a simple, effective electric toothbrush.
I now use the Philips Sonicare 4100 Series every morning immediately after getting up and in the evening before going to bed. I am very pleased with it.
The toothbrush fits comfortably in the hand and is very easy to use. No complicated settings, just turn it on and brush. The timer helps me brush long enough without having to think about it. I notice that I really use the full two minutes thanks to the timer.
After brushing a few times, you already notice a difference. My teeth feel cleaner and smoother than with a regular toothbrush. I also feel like I am more consciously focusing on brushing properly, partly thanks to the aforementioned timer.
The only minor drawback I find is that the brush heads are on the pricey side to replace. The recommendation is to replace them approximately every month.
For me, this is a toothbrush that really works well; I will certainly continue using it, despite the cost of the brush heads.
