I had before a Remington with touchscreen accurate to 0.1 mm. I have a very short 3 day beard for years and I have really tested.
It did the job but I put 2 to 3 times longer to make a clean and regular work. Maybe she rotates slower or that the blades are inefficient.
I am 0.5mm for me so to a minimum and my beard is longer than on my previous trimmers, so small error in short stature perhaps.
In short it's really not bad for the price, if you have a small beard that does not sting it will not cause any worries :). Otherwise it will lack efficiency will require a lot of passages ...
