Unfortunately, it is for single use..... after the second time, it started pulling and tangling the hairs instead of cutting them.... it only has 3 options 1-2-3 mm.... it seems sturdy but what good is it if it doesn't do the job.... I spent less money and got a machine (fakir stubby) with many adjustments (0-10mm in increments of 0.5), without the hassle of attaching and detaching accessories.... One star only because it has a digital battery capacity indicator.... but what good is it if it doesn't serve its purpose....
