I am new to this, so hated it the first time I used it. However, the second time I used this clipper, it was much easier. The head of the clipper gets hot, but that doesn't seem to effect its performance. The first time I used it the guards kept getting stuck in my dog's fur. So I used it mostly without a guard this time (just human comb to guide me by), and it cut the hair like a hot knife through butter. I went all over the dog with a guard afterwards and it stuck a bit, but it was where there were matts. I guess that was the problem the first time and I didn't know. So for a first timer, I'm quite pleased. I'll be saving money by my fourth trim too.
