Quality Time Neck Hair Guide SuPremium, The Original Neckline Template for Shaving and Keeping a Straight or Curved Neck Hairline; a Line Up Stencil/Guard for Neckline, Do-it-Yourself Made in USA

Good product and works well especially if you are cutting your own hair.

Easy to use and choice of necklines (straight or arced)

This is such a simple and easy to use tool - I'm angry at myself for not buying one sooner! I use this with my wahl clippers to get a perfect neck edge line. The band can be a bit awkward to place as it goes over your face and looks a bit goofy in use, but the important part is it stays in place and keeps the edge very straight. I ended up using the flat side - when pressed against your neck it will "curve" a bit up at the ends anyway, so keep that in mind.

Very good product does it’s job on the back of my hair when I’m doing lineups play around with a little bit it’s really good

I've cut my own hair with a Flowbee for many years and always had trouble with the hairline on the back of my neck. This is the PERFECT SOLUTION. It offers options for rounded or squared patterns, and it is easy to make a symmetric cut. I'm not as flexible as I was when younger, but I can now finish this step in just a couple of minutes.
