Had to submit a hair clipper with battery, I bought then at Aldi for 29.95. This was contrary to this hair trimmer here a lot harder, plucked strongly and was just scrap! This one is cheaper, and is not plucked super lightweight and comfortable to hold! Knives cut very well, but you should go with thick and long hair twice on the spot to be cut. I'm very satisfied with this unit, considering what this device costs. For personal use this trimmer is fully sufficient. Length adjustment is totally easy and is easy to use TOP and strong buy recommendation
