Things I liked: Nothing
Things I would have changed: I would change the whole thing altogether, i got a a defect.
What others should know: I ordered this pump for my pcp rifle and from the beginning it was pumping air too slow or barely pumping at all.After a few months of use.It wouldnt pump at all no matter how hard i tried.Finally i tried to dissassemble it to try and fix it. But its sealed waaaaay too tight.I still cant fix it to this day. And my warranty is gone.
