Based on the reviews and previous experience I had with a hair clipper from the same company, I ended up purchasing this particular model. Its performance is mediocre, especially when it is not plugged in, whereas it is more efficient when it is powered. Its battery drains relatively quickly after 3-4 haircuts and beard trims. The money you spend is quite high compared to the performance of the hair clipper.

I highly recommend it. It is only 0.5mm in size. It has 3 sizes of attachments: (A) 1mm to 10mm. (B) 11mm to 20mm, and (C) 21mm to 30mm, with 0.5mm in between (e.g. 1mm/1.5mm/2mm/2.5mm, etc.). It also has an attachment for precise trimming between the chin and the lips (soul patch). Precise trimming for short, but also for long mustaches/beards (after all, that's what the model successfully targets). Easy to clean. Powerful machine. Charges quickly. Precise trimming. The best machine I've had to date.

Very good machine for shaving, it easily cuts even the toughest hairs. When using it with the attachments, it may get a little clogged, but you just remove the nozzle and continue. Simply unstoppable. Cutting depth is 0.5mm without an attachment, I believe.
