Things I liked:Everything! Much smoother than traditional spring. No twang, just a solid thump.
Things I would have changed:Nothing
What others should know:Makes cocking a tiny bit harder, gets easier as you go.
Things I liked:Smooth and makes it quiet.
Things I liked:This is installed in my .22 cal Gamo Whisper. It is smooth, low-recoiling, quiet, and powerful. This sure beats my mechanical-spring air gun.
Things I would have changed:Not a thing.
