I have to say they CAN fail. I had one completely blow out on me. I shot it at a target around March and the screw that holds the blade to the tip blew out and the blade popped out the side. The arrow didn't go far into the target because the blade was sticking out sideways. I'd hate to do that to a deer. NAP tech support emiail does not work. I tried for months and got no response. I called asking if i could buy the screw to put in the blade to fix it and the guy said he would go out to the shop, grab one and mail it to me. I thought that was pretty cool. The next day he called back and asked if I had the red or the black heads. Last year when I bought these I bought the red. Then I heard there was a problem with screws not staying tight on the red ones and to return them for black. Turns out it wasn't just the red ones but it could easily have been my fault for not checking the tightness of the screws because i didn't. So, because I told the guy that story he said they were just going to send me the 4 pack. The 4 pack is 3 broadheads and a practice head.

In my opinion they did not shoot like field points. one kept shooting low left or low right, I don't remember which. I'd switch the broahead out and put a field point on it and it was straight again. That was out of my crossbow. I'll find out before too long about my new Diamond Air Raid how they shoot out of it when I get the Blast arrows I ordered. If anybody gives a crap about that I'll write up a review on it when I get it shooting since I haven't seen any yet. I have to do some adjusting with it first. I will be sure to check back in though. I'll upload pictures of the broadhead when I get home Monday as well in case anyone is interested in seeing what happened to it.
