They are decent. Fly well out to about 20 yards. I can't get them to fly worth a darn past 20. I sighted mine in by shooting a fixed blade broadhead, of the same weight, to get me in the ballpark and then switched to the guillotines. Make sure you are shooting them into an open-layered foam target. Good luck with them, they are ultra effective when you hit the sweet spot.
