Buy them, the hole you get is very impressive, There isn't a head on the market that can do what these do, if there was I'd have them. Take the chance I did, I was a muzzy man for years until I got these, they don't look like much, but believe me they are awesome. They were more accurate than my muzzy's and my muzzy's were even tuned for my bow. I'm very specific about my stuff, when I saw this, it was amazing. Buy them, you'l be very surprised.
