Things I liked: Feels like a quality product. TO6 trigger is very good.
Things I would have changed: Recoil pad is hard plastic. It feels slippery and cheap. I'm thinking of changing it to a rubber one. Open sights are plastic and don't feel too solid.
What others should know: It's quite hard hitting gun. Cocking starts feeling heavy after ~50 rounds (I'm an adult male). Recoil is not smooth, but it might get smoother after a while, I think. I would recommend this as a best value air rifle for hunting. For backyard plinking and target shooting you might want to consider some lighter and less powerful rifle, for example, Beeman R7 or similar. Only 3 stars for accuracy while I haven't tested many pellets yet and can't give a good opinion about that at this point.
