There are a lot of reviews on it on archery talk. Most seem to like it but most also say it takes a little time to get used to. I wouldn’t change this close to season.
Aaron, the guy who owns it, gives a 30 day money back guarantee so you really have nothing to lose by trying it. They Ranch Fairy on you tube(he is a goofball) likes it a lot and probably has a very in depth review of it.
