Yep,, been doing that for decades now.
It isnt really, just not as easy because you cant see the back.
I don't use those at all, just mow it back to a stubble. That's easier because you can feel how long it is at the back because you can easily feel the bit you have missed.
I don't even use the combs at all anymore, just do it without them.
Like a buzz cut. It grows out quite quickly and imo looks better than the bare skull effect which needs daily maintenance. F*ck that. Same with the face..
