No experience with them but when it comes to fixed blades I buy cheap and test fire each one with the arrow it will be mounted on before hunting with it.
Have had great luck with Muzzy's but every now and then I'll get one that just doesn't fly right.
Guys go crazy over broadheads but for fixed blades the only thing that really matters is that they are sharp, fly straight, and what their cutting diameter is.
Never had a blade break on me and 9/10 times after a couple passes on the stone they are ready to go again. When I do jack up a blade enough that it's garbage replacements are dirt cheap.
Wouldn't hesitate for a minute to fo on that deal.
