It hardly opens enough to put hair into it, doesn't cut like it says it would. i brushed my hair before even opening the box and i brushed the sections before putting it into the machine and it still pulls out hairs and those get caught in the cutters. Plus the "dead ends" that its supposed to cut and collect, it doesn't. its just an opening not a compartment, and next to nothing was in it half way through the first half of my hair (i have very thick hair and i was doing very small sections to put into the machine) Not worth it. Simple and plan designed, just go to a hairdresser in person or do a conditioner treatment.
