wonderful. only small problem is they sometimes rub underneath the jaw. the three different sizes i've had for my lot (shetland, welsh mtn, and big warmblood) i've just glued a strip of a bandage pad, the gamgee type ones. Between the two cheek straps and folded over the top to ensure it's all covered.
hope this helps, i would still recommend them.
i have a pink one, and id be at a loss without it! I had a problem with it rubbing this nose, but i also glued a strip of fibregee and its stopped it! i also put it over the head strap, so it wouldn't rub!
