Summary: One of the best features of these trimmers is all sizes in one guard. Over the years I have found the most annoying feature of hair clippers is all the gaurds to keep track of, whether the dog eats one, or you loose one, these trimmers bypass that problem. With a single adjustable guard you never risk loosing a guard because you don't need to change out gaurds for different lengths.
Pros: all sizes in one guard, cordless option, few parts, elegant design, rounded guards
Excerpt: I have used this product for about several weeks now and it works well. I use it predominately as a beard trimmer and I like the fact it has 1 adjustable length setting without having to clip on and off another length setting as other products. Also don't underestimate the convenience of having a cordless clipper I will never buy a corded one in my life. From a performance perspective it works well, and the battery life is more than sufficient to get the job done.
Summary: I am very pleased overall with this trimmer. The adjustable length guide is a great feature. The locking mechanism on the trimmer could be a little more stiff to unlock but it still performs wonderfully!
