Brushing is clearly less "tiring", is gently pass the brush on each tooth. The timer is great: it now takes regulatory 2 minutes from the 4 areas. 30 sec each.
At the end of brushing the result may not be visibly different than manual brushing but he probably was more effective in places such as rotation with these hairs go better between teeth. This is brushing lines recommended by dentists.
The Professional Care 1000 is I think the best quality / price ratio. As previous reviewers have said, I'm just confirmed. A more powerful engine compared to the first range. And a visual alarm in case of too much support. The higher versions provide for me as gadgets (different brushing timer ...).
The first load is very long, almost 24 hours. But then it takes one week at 2 brushings per day. I regret the noise, I find it quite noisy!
