By Arthur from USA on 2008-08-30 20:35:30Things I liked:Very smooth, nice "thump" at discharge with no other noise. Very easy to install, took about 15 minutes. Accuracy remained unchanged. Very smooth and no noise during cocking.
Things I would have changed:nothing
What others should know: I installed this kit in a new Diana 48, in .177, I had already tuned this rifle and was using the factory spring. The factory spring broke after several thousand shots so I installed this kit. Factory spring was giving me 1039 avg. FPS with SD of 5.83. This kit after 280 shots is giving 968.0 avg. FPS with SD of 6.77. This is 71 FPS under the factory spring, no big deal, shoots nice.

By Vernon from USA on 2010-08-17 20:59:24Things I liked:Installed this into an RWS 34 Panther which is a well damped air rifle from the factory to start with. Shooting RSW Super domes it went from 926 to 940 FPS and shoots Predator PolyMags at 853 FPS (they shoot flatter for me). Analyzed audio recordings of gun before and after spring installiation. It does not make retort of the gun any quieter but it does dampen the spring noise. After the initial bang, there is less audio energy and it decays slightly quicker. You can feel the difference, what little spring bounce I had is gone. Also the spring noise from cocking is gone. If you need to replace the spring in your rifle, definately consider this. If you have a rifle that has a lot of spring vibration, get this spring now.
Things I would have changed:Tune it for the heavier pellets.
What others should know:The Panther has a synthetic stock that does not vibrate like some of the wooden ones do. The improvement should be much greater for those guns.
