Thankfully it turns out that this device is all that you need. It is solid and does its job without chirp. The hair length adjustment works also reliable. The only drawback here: I would like to see an under-3mm-position.
The lowest setting (except, of course, without attachment) corresponds with me about a 5-day beard, which I can not find too maintained. Without attachment, it is then again a little badly short.
A short-hair cutter is something over which you actually can write quite a lot. For this device I can not remember a lot. It is what you would expect. It is a revelation to have not been laying around a charging cable. It is a revelation to be able to use it in the shower.
I would recommend this Anti-frills device so in good conscience.
