I have a grey horse and take grooming very seriously. At first, I didn't see the hype but after a few uses it grew on me. I use it as one of my last brushes because it grabs the last bits of dirt and dust.
My horse is sensitive and would shy away from my stiffer, post-curry brushes. Now we do a quick flick brush and then go straight to this one. She loves it and it does a beautiful job. Feels luxurious to me too!
This brush is in my opinion the top show brush of them all. The shine it produces is better than any. Have used for over 40 years.
