I'm not a fan. We have some at our store. We hardly ever sell any of them, partially because I can't honestly recommend that anyone buy them. The leather quality is not what I look for, certainly not for the price they charge.
I was actually just at a trade show and I was looking at this stuff. I didn't check out specific prices, I didn't think they were too pricey, but I decided I'd rather spend a little more money on something a little better quality. The stuff is OK, and I did have some collars in hand that I was going to buy, I just decided otherwise.
