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

Great but Pain
It’s alright, does the job as it is supposed to. It’s easy to use and helped fix my Uniqlo jacket that was all matted. It didn't restore it to it's original form however it did unmat it. If I bought this way before and touched up the jacket, I think it would of been perfect to this day still. Maintenance of those jackets are a must! The brush is strong and works well for fluffing it up because of the metal wiring. The only bad parts are that it can hurt if you accidentally poke or scratch yourself, I actually got cut by it when I quickly was brushing. It’s kind of hard to get the lint off the brush but it's better than others and might hurt because of the metal. But overall, it’s a cool tool that makes my jacket fluff again!

Works well, however…
Purchased this to give life back to my Sherpa backed blankets. This is a well made brush handle is comfortable. The teeth are strong and durable. They did not bend around while I used it and maintained its shape. The problem I guess I’m seeing is that it doesn’t get deep down into the fabric to it’s just a surface “petting”. Maybe if the teeth were further apart or something. But does seem to provide some form of fluff.

Very useful
Works great on polar fleece. I also use it gently on. My jeans to get rid of dig hair. Speaking of dog hair, I have been known to run this gently over the dog's coat.works great for that too.

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.
