The brush cleans very well, better than I have ever hinbekommen with a manual brush.
It lies well in the hand and is simple and compact.
They can also take on vacation without problems.
I have only two small problems to notice.
1) You have to reload quite frequently. 5 days are as specified in the product description very optimistic. At the end of the battery life of the brush head is no longer pulsates strong enough, so you have to load the brush already again even before it is fully discharged.
2) My partner has an expensive toothbrush from Oral-B and this shows a flashing LED indicates whether the brush needs to be charged or not. This feature I miss painfully at the Precision Clean. However, I must say that I like to renounce this "gimmick" given the price.
All in all, I recommend the electric toothbrush with a clear conscience. Concerns should any buyer that the brush heads vigorously cost money, so you do not get cheaper than manual toothbrushes. Electricity included in the calculation, probably even more expensive. The cleaning power, however, has convinced me that the reason is that I will not soon return to a manual toothbrush.
