Compared to all the older models that I knew that power is sensational. Gentle cleansing with the standard head, subjectively also good for your gums and the spaces. It almost feels like a thorough, pleasant 'irrigator'. It would appeal to me time to try the polishing heads additionally.
As described by others, I find 2 minutes, too short, if you like going to tooth according to the instructions of tooth. But no problem, because it is very pleasant and also so I let me just once more time, often 3-4 minutes.
I can also be a 'blind purchase' only recommend this device. I was at it, read all about outrageously expensive sound and even ultrasonic brushes. In the former, there are very good models, the latter go the reviews extremely apart. Eventually, the technology is not so reliable, so too many loss products on the market. Anyway, with this brush the problem is solved and some reliable in the house - maybe even permanently, because simply too good.
I tend to like the view of Stiftung Warentest, that a better cleaning result is hard to achieve. Certainly some sonic brushes are faster and more comfortable, but the fact remains that quite perfect dental care for under 20's to have.
Simply amazing. My compliments to the manufacturer, such direct hit are impressive.
