Killed my appetite the only time I ordered it. I haven't had a complaint about the other sauces. You might want to try it before buying a bunch. It was hot, but not real tasty.
I usually get the Wild sauce which is one step below their hottest, Blazing, at Buffalo Wild Wings.
I always get their boneless wings. Once I ordered 6 Wild and 6 Blazing. WOW. The blazing was so hot that I would eat one of the Wild just to cool my mouth off!
Each of their sauces steps up the hottness in reasonable degrees, and then you go from Wild to Blazing and it's not even close.
