OH MY GOODNESS... These are the best clippers I have ever owned. I have a shitzu who is 12 years old and throughout our time with Chachi, he has gone to dog groomers and I have cut his hair myself. I started cutting his hair more often because I was told he was very timid at the groomers. I would buy clippers from retail chain stores and although they worked fine, Chachi was still shaking of fear. They would get loud and were quite noisy. WELL, after reading reviews on these clippers I decided to buy them....I was surprised at the low level of noise and vibrations. I was very impressed with the smooth cut it gave. Since Chachi is both inside and outside, his hair can get a bit rough, nappy and coarse but these clippers breeze right through his coat, like a hot knife through butter, (NOTE: not that the clippers get hot, they just work great).
Would highly recommended to anyone who is grooming their dog. Oh and the fact that they are cordless makes it super easy to use.
