Definitely not suitable for those who have a thick, dense beard. I let go a length of about 2 cm, I usually wear 1 cm, in 1 pass the machine is not able to cut 1 cm of hair, the motor does not cope noticeably, the knife gets stuck, I had to remove 2-3 mm, with a narrow knife it took a long time, a small nozzle is bad raises hairs, you have to go through one place 5-6 times, and still leaves a lot of separately sticking out, as a result, I had to shave off without a nozzle on the eye at all.
