The worst machine I have ever used. It took me an hour to trim short men's hair, as I had to go over the same spot again and again because it simply doesn't cut and just slides without catching the hair. Another downside is that the comb on the back side, which touches the head, has an opening that is not visible in the photos, resulting in hair getting stuck inside and clogging it without cutting. Not to mention that after removing the comb and touching it to the skin for details, it caused a burning sensation that I couldn't even imagine before touching it, and I paid 50 euros for it... I wouldn't take it even if they gave it to me for free... frustration is simply what this tool is, and the funny thing is that it says "precision blades for quick and easy cutting" in the details. Hahaha
