Review (5/5): Wow does this thing work!
I have a cat that's built for snow, with a downy undercoat that sheds a lot. We live in a cold climate which unfortunately has been getting noticably warmer in the past few years, so it feels like shedding season never ends.
A Canadian YouTube channel recommended a certain type of undercoat comb, but it's quite expensive so I got this as an alternative. The comb that was recommended had a small bumpy edge, but this one actually comes with two: that style plus a tine comb edge. To my surprise, the time comb edge actually works a lot better than the bumpy edge. It gets an amazing amount of fluff off and I'm happy it won't end up all over the sofa or floor.
It feels a little weird to hold due to the boxy shape, but it's very effective, easy to clean and super affordable. It seems to be very durable too. I would recommend this to anyone with an extra fuzzy cat or dog.
