I've been using these chunkers for a few weeks now and the 26 teeth slice through heavy undercoat without snagging. The 8-inch length gives me great control for blending, and the action is smooth right out of the box.
The 26 teeth glide through thick double coats without snagging, and the 8-inch length gives me way better control on bigger dogs. Took off a matted undercoat in about half the passes my old thinner needed.
The 26 teeth cut through thick double coats way faster than my old 10-tooth pair, which saves me real time on doodles. Only gripe is the 8in length feels a bit long when I'm doing tight work around the face and paws.
