After using it twice, I put the machine in its case and it starts working on its own without touching anything. It's bad that it has a sensitive sensor and not a start button. The stupid thing is that I've already ordered a second one as a gift. Maybe the instruction to put the head under water is wrong because it takes a long time to dry and maybe it messes up the sensor for many hours afterwards... I'll see how it goes and I'll only use the brush for cleaning. It doesn't stand steadily wherever you put it because its base, due to the silicone-door cover, is not flat. For now, it has caused irritation in my armpit area, where I had very few and soft hairs. (I have previously done laser hair removal)

Moderate results. However, given that it is a very convenient little machine for travel (small size, charges with a phone charger, good battery life) and not for main daily use, it is considered satisfactory. In no case can it be compared to the branded large and of course much more expensive shavers and replace them.
