In addition, the life of the brushes is excellent and the price is quite reasonable compared to other brands.
It comes with a travel box for a 2 brush tips inning.
Fully charging the battery allows widely held one week; so we can go for some days without taking the charger.
There are 4 brushing modes: the first two (2 speeds) to adapt the brush depending on your sensitivity to vibrations, the other 2 are more gadget and unnecessary in my opinion.
A pressure sensor is light a red LED on the handle if you press too hard: the interest is learning to exert sufficient pressure for effective brushing without much support what deteriorates prematurely hair from the Brushless improve brushing.
A product that I recommend.
