Ignore the other reviews ..these are actually pretty goodI have medium thickness hair and give myself a crew cutThe clippers work well to do this. and pretty much all the hair is captured . I have to empty the container a few times per hair cut - You can unclip the tray pretty easily or just shake out the hair from the deviceThey are quiet - like a beard shaver - the fan make a bit more noise but quieter than normal level conversation. you would not wake up someone else in the house. They are not noisey like mains/barbers clippersThe instructions are ok - they are in Chinese with English underneath ..I posted pictures of the manualthe power button can be a bit tricky to use sometimes- but this stops accidental pressing.1 press - very quiet clipper2 press - fan 1 and clipper3 press fan 2 and clipper4 press offthe tray easily clips off for emptying.also to use the attachment guides - there are 2 length settings per attachment - just put it on one way or the other.I'm not sure what is causing the other reviewers such difficulty using these clippers :Dhope this helps other people:)
