MANGROOMER - PLATINUM PRO New Self-Haircut Kit and Advanced Hair Clippers with Lithium Max Battery, 9 Length Guards and Included Bonus Storage Case, 2 Piece Set

I use the Mangroomer myself because it does NOT have the curvature which allows you hit every area of the head.

I have the Mangroomer version and it's easy peasy. I also use it for keeping facial hair trimmed so it's my all in one shaver.
