Things I liked:BEST add-on to the Sumatra 2500. Original fill plug was a serious problem (in my case at least).
Things I would have changed:Nothing.....perfection!!!
What others should know:Highly recommend this product....at least if you don't want to waste air. Total and quick fix for a faulty fill plug that came with the Sumatra 2500. Replaced in less than a minute.
Things I liked:Does exactly whats it designed to do: add a simple to use foster fitting to the Eun Jin Sumatra (and the Sam Yang Guns too) in place of the irritating factory fill probe. Just unscrew the old fill port and screw this in. Two minutes later you're filling without leaks or fiddling. Especially nice for those of us who hand pump and don't want to loose our hard work to a fiddly o-ring.
Things I would have changed:It seems a bit pricey given the simplicity and small size of the product. I guess that's the price you pay for a specialty part.
What others should know:If you hate fiddling with your factory fill probe, tweaking, replacing o-rings, fiddling, jiggling, etc... This will make all those irritations go away. The included rubber dust cap is kinda cheap and you will likely loose it fairly quickly.
Things I liked:This Foster Quick Disconnect and the O-Ring worked great. I have put one on each of my Sumatra's .22 and .25 2500. Took about 1 minute to install. Happpy to get rid of the male fill probe that came with both guns and the leaky o-rings.
Things I would have changed:Not a thing. Should have done this a few years ago.
What others should know:Just be sure not to tighten it down too much or it could leak. No need to compress the o-ring excessively. I over tightened the first one I put on and it leaked.....just back off a bit and everything was fine. Suggest just putting it on and begin to fill the gun with HPA. If you see/hear that it is leaking then tighten a little until the air does not leak as the gun fills to 200 BAR (3000 psi)
