These Brushes are amazing and my horses' response to it was great- I bought one for a barn friend too!
I didn't realize how much my OTTB hated other curry brushes until I tried this one. When I use this one, he drops his head, blows, and relaxes into the groom. No tail swishing, no foot stomping, no head tossing -- I really am blown away by the change in his behavior. I've also tried it on several other grumpy groomers with the same result - happy, relaxed ponies -- and did I mention it does an amazing job bringing up the dirt!
