So low-tech it’s foolproof.
Been cutting my own hair since Covid-2020. Added these to my DIY arsenal and what can I say other than they work fine, and exactly as you’d imagine. I can achieve a decent 3”-to-2” layering all by myself. I never use the 4” one though, and I can’t imagine most men would, as that is pretty long. Maybe one day I will modify it myself to a custom size like 3.5”, 2.5” or even 1.5”.
