Wasn't expecting a snap-on comb to feel this solid, but the wide metal teeth cut a clean 25mm every pass. Clips onto my clippers tight with no wobble, which matters when I'm squaring up around the ears.
The metal teeth glide through my doodle's coat without snagging, and the 25mm width gives me a consistent 1-inch cut every pass. Snapping it onto my clipper took two seconds and it stayed locked on the whole groom.
