releases archery

I've talked to many people who use these Broadhead but no one has used them, my dad said that archery 3 stores say they are trash, and are deployed in the air and the accurasy leg, I think it must be of the impression of being released, but does anyone shot them and he did hit acurately? i shot a 25-yard range and hit way low and left, hatred harm the animals and harvest, but it happens sometimes, but I wonder if someone has had the same problem? Did I just waste of $ 45 and I get something else? what do you recommend?
Shot 100 grain 2 blade rage heads wide. I love and have killed many deer with them. I would like to keep and tell your dad is an idiot!
Compound archery, release punching.
