It has a much lower frequency and softer sound than my old clippers and I love the shape of the case that make it easier to hold. If you want to use the clip on guards/combs you need to have a #30 blade as they will not work with the #10 blade that comes with the clipper.

Watch the sizing

The sizing runs a bit small, my dog was in the middle of the sizing for small but the wraps are a bit small but still fit. If its in question go a size up.

I've been trying to cut my doodle's hair using a #10 and attachments but it kept getting clogged. Then I realized that there were blades with different lengths so I bought 2 sizes and it cut through his hair like a dream! I'm a DIY home groomer.

My favorite 7 blade

This blade arrived to me sharp, not dull, it works so well on matted dogs without struggle, and the blade stays cooler for a longer time than my other 7 blades.

Little frustrated with this blade. Brand new out of the package. My clippers just had a new blade drive places and my other blades worked fine. This blade would not cut the hair. Hair was not matted and was washed, dried and brushed.

I bought a KM5 clipper about ten years ago, when the heavier clipper I was using became hard for me to use for a whole shavedown. I've used it on three standard poodles, two at a time, all these years, and only had to replace it last week.
