stock spyder valve- better
NPS neo power valve- good
RAT valve- good
Marker Setup:
Spyder Shutter with lots and lots of stuff
Strengths:
this valve has no good points in my opinion. it did not work in my shutter. my gun would not recock at any pressure with this valve in it. it also leaked a bit.
Weaknesses:
this thing had some kind of metal filings in the package which really scared me. and it did not work PERIOD. i took it to my local shop to see if they could fix it and they said to return it becaude it may have ben defected. it probally was but i just got my money back and got a new X chamber instead. buying this valve was a compleat waste of my time!
Conclusion:
DON'T BUY THIS SO CALLED "VALVE"!!!! it is garbage. i would opt for an NPS or a rat valve. maby mine was defected, but i would not take my chances with buying this one.
