I shot impulses with RIP valves and impulses with stock valves.
I have an impulse with function trigger, function bolt, function valve, All American Barrel, ccm claping feed neck, Custom products snatch, W.A.S. Board, CP rail, and CP A.S.A
The key strentghs are that it lowers the operating pressure significantly
putting it in the gun without trearing the O-rings on it was tricky.
It was a good buy, it lowers your operating pressure from like 190 to 100. I found that it shoots at a consistent velocity with no drop off. Overall i think it is a good buy and a good upgrade. It will help you save on your air costs due to the lower opperating pressure. Nice orange color, but the color dosen't mean anything you never see it again once you put it in.
I would recomend buying, it will help you save on air costs.

Anodizing looks good - besides that, nothing - leaks like a sieve
Leaks - manufacturing didn't allow for o-rings
The main issue of the valve is that it leaks. The design requires the use of the stock valve spring to create pressure on the valve stem to close the valve during the firing cycle and keep it closed when not firing. The problem is that the pressure from the spring and from the input pressure from your regulator is not enough to fully seal the valve to prevent leakage down the barrel or in the breech. I have attempted a stiffer spring, lubing the valve stem, and adding o-rings to seal the valve - nothing worked. I am not a newb, and have worked on SP Impulses ever since they were first produced. I love the markers, but am not a fan of this product. I would suggest using the stock valve over this product or the ND RIP Valve....Function forgot their name in making this product. A product should work when purchased brand new, and this one just doesn't do that.
** Side Note ** I luckily have access to machinery tools, and added an o-ring groove in the side of the main valve plug. I used a size 14 (you could also use a 15) nubile 70 durometer o-ring to create a seal when the valve is closed. This worked in eliminating the leak.
Don't buy it. If you want an aftermarket valve, go with the ND RIP.
