I love mine. I notice more of a horizontal feeling recoil opposed to a vertical (muzzle climb) type recoil. Two things though. It is LOUD and you will feel the blast on your face and chest. Nothing bad, but if you've never shot with one you might be suprised by the first few shots.
Also, I have this mounted on a one of Denny's RECON barrels with a Samson rifle length 4 rail forearm, a TD vertical grip, a YHM bipod mount, a Harris bipod, a Troy front flip sight, 6 TD rail covers, and a scope that extends out pretty far. It is pretty nose heavy so my perceived recoil/muzzle climb will be different than someone with less equipment on their rifle.
I say get one, try it, and if you don't like it or it doesn't meet your expectations, then sell it. I'm sure someone will buy it from you.
