I've got one pair of the boots and really like them. I'm going to get another set so that I can ice all 4 legs at once. There's not anything negative about them, super easy and quick to use.
I agree with the post before me. I do like them but I dont think they are worth the pricetag. I honestly feel my horses work 10x better when I use my PHT products (quick wraps, 3 in 1s etc) than when I use the IceVibes.
