It even comes with color-coded pieces so every user can remember their perfect length.
Promising review: These clippers come with everything you need to do home haircuts, including a full color, step-by-step instruction guide with tips and techniques for cutting hair, trimming brows, going around the edges, blending, etc. They're very quiet when they're on! My son is autistic and if I have any hope of cutting his hair myself, the volume of the clippers is going to be a big factor. I think these are the quietest I've heard. The guide attachments are really easy to snap on and take off. I LOVE the different colors and how you don't have to rifle through the whole box looking for the right ones. It's also very handy that they have the color guide printed on the body of the clippers so you don't have to reference the manual every time once you know how to use them. Just reference the handle, grab the right color and off you go! All in all this is a great product and I highly recommend it, especially for beginners like me! " —Kate Mahoney
