I've used them and had no problem. They actually copied the Rocky Mountain Gator broadhead. Basspro bought them out and now they go by Blackout gator. Basically the same broadhead, only you can get them on sale for $19.99/3. This is what i use. Been using them for years. There's not a broadhead on the market that wont put a deer down quickly if you put it in his boiler room.
