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.
Pros: all sizes in one guard, cordless option, few parts, elegant design, rounded guards
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!
