Clipper Guard - What is the best Guard?

What is a speed-o-guide? If you haven't heard about it, it's a guard that has the most stability, versatility and durability. Sometime cutting hair can be a hassle to those who don"t have the right tools. The guard is one of the most important tools of cutting hair. Having a proper guard is important because it create the look you want, whether you want your hair long or short the guards are what create those levels.

Personally I have had many experiences of "bad guards" falling off and creating patches in my head. Horrible, Horrible. When I got the speed-o-guide I did't have to worry about that, it was hard enough to get the damn thing on the clipper but when it got on it dose it's job.
