Very good machine, used for amateur purposes. You can easily make it zero gap. However, it pinches a little when there are a lot of hairs, so it's good to do a quick pass and then take them off as much as possible with a trimmer. It doesn't understand anything and yes, it's worth its money. I have shaved so many times and it still hasn't needed charging. It even has 2 blades(!), one in the shape of a T. Update: Indeed, the autonomy of the machine is incredible. However, the T-shaped blade pinches the hairs. The other one is better. However, it is not able to cut the hairs if it is not positioned exactly opposite to them. The Philips BT5270 that I had before could do it. Unfortunately, this is a disadvantage. However, if you get used to it, it's not a problem
