"Not a fan. First they're so bleeping small that they're hard to hold onto, especially with any silicone oil on the valve. A certified bugger to try to slip over the end of the fill valve! I tore three of them. If you can get them in place they seem to work as advertised (for now after 1 or 2 fills) but I think a little more development is needed. A slightly larger version would be a thought.

"Got some for my double eagle rebranded jag arms shotgun(they are known for the leaky gas tank in the full stock) and it works flawlessly now. Also if u want to a cheap, reliable, gas 3/6 shot shotgun, then check out the de rebrand of the jag arms scatter gun.

"I really have nothing bad to say about these, and have no regrets about my purchase. They do their job and save me a lot of money on gas and propane even when using a low quality fill valve. However, do not expect these to fix 'leaky' mags, that is not their job. To fix leaky mags, take out the valve itself and wrap all threads holding gas in with teflon or ptfe tape. Bought these for my WE 226 mags and they work great! Definitely worth the extra dollar to support breast cancer and, hey, they're pink!
