Works great, faux fur blanket is like new again!
Just used this on a faux fur pet blanket that I have had for 2 years and never brushed. It worked amazingly! Since it was so matted it took a bit to do the whole blanket (50” x 40”) but short strokes got it looking like new very easily. Some fibers came out in the brushing along with pet hairs, but the rug shedding was minimal.

O. M. G. It worked so great!
First, let me say, I'm not getting paid for this. This is personal experience. I was about to discard this rug. 1. It's old, like 13 years old. 2. It's been in storage for 4 years. 3. It's matted, as you can see in the pictures. 4. It's brown. Them I saw how much rugs are!😳So I had to come up with something. This was cheap to see if I could salvage it and not spend over $100 on a new rug. The dirt and lint that came out was gross. But as you can see, I was able to make it look new-ish again. I'm keeping the rug and this brush! I have other sheepskin rugs that are smaller and brand new, so this will come in handy.

Recommend
Worx better than expected. Much improved the appearance and texture after washing & drying my 6 sheepskin pelts and three faux sheepskin pelts. There’s always a natural shedding after a cleaning, but this DEFINITELY decreases those incidents I recommend.

Great for blankets
Great for making sherpa or fur blankets soft again after wash. I imagine it'll work well for fur hoods as well. It did a good job of removing lose hair fibers and the quality is good, even if it's extra spikey. Overall, affordable solution and good looking brush to rejuvenate faux fur
