One of the best!!! I have a Griffon Canis with very dense fur, all the machines I had tried were getting clogged and I was struggling for hours, both me and the dog!!! With this one, I shaved him in no time, wherever the machine passed, it took all the hair at once!!! The only negative is that it has a very short cord and the battery doesn't last long! And be careful!!! If the cord gets strained even a little, it breaks! I found another identical cord and replaced it! Overall, though, I am very satisfied with the performance of the machine!!!! It's worth it!
