Professional Hair Clippers/ Beard Trimmer Set For Men

What was the number on the screen?

Can you adjust the lineup machine like to skintight cut?

I just got those

You showed how to adjust the blades up and down with the raiser on the side of the clipper, but what is up and down setting? Like if its up and I have the 10mm guard, is it at 10mm or its at 10mm + the raiser that would be 3mm I think?
