I've used them for a few years now. I love them. I've killed three of my ten this year with the same arrow and broad head. It's still good and plan on using the same one next year for a few more kills. I only ruined one arrow because of a screwed up shot. Clipped a rock in my from landscaping. Ooops forgot that the darn thingwas there. Arrow veered off course a little, sheered off a blade on the broad head but stuck the deer in the hind qtr. Left him lay overnight and found him dead in the morning 100 yrds away. The little stinkerbent the arrow when he pulled it out.
