I like the look of these broadheads and thinking if trying em out.any issues with these besides shot placement.also not worried about durabilityi will buy new heads on every deer if they perform.
I hear they have a lot of mechanical failures. Apparently, there's nothing to keep the blades open as they pass through a deer and so you get a very small channel to form. I've had a lot of luck with Spitfire Maxx broadheads if you're interested in some expandables. Their design is simple, hitting the deer opens up the blades. The friction plates let you adjust them so that they open with enough force for an impact, but not so little that they do so during flight.
I have a good friend at work who uses these heads, loves them. He took 3 deer with them last year and watched them all drop. He has been bowhunting since before I was even a thought. Now, that said, and based on his advise, I bought some. I got them cheap so no worries. However, in testing, watching them open in video and just looking through the action I figured this much... When they initially hit, they will penetrate still closed and not open until they reach the chest cavity. Even then, with an extremely light and fast arrow, they may not open at all. If you have a heavy, slower moving arrow they will react much better and should do some major devastation. That is just my opinion and my best semi-educated findings. After playing around with a few different broadheads, I settled on 2 blade bloodrunners. After that, I would have gone with grizztricks.
