"You'll spend more time fixing jams than shooting. I have never gotten it to make it through a full wind out without jamming at least 3 times. There are YouTube videos on how to fix the issue though, I havent tried them yet, I will update my review once I do, but you still shouldn't have to modify something thats brand new just to get it to work properly.

"Doesn't feed reliably. Or, more accurately, reliably doesn't feed. I've literally NEVER gotten it to feed more than 4 BBs at once; they always jam up as they move from the reservoir to the feed ramp. I was never able to unjam it without disassembling it at least partway.

Mine also came with an entirely missing feed lip spring, so it doesn't hold itself closed. Luckily, though, this mag is incapable of reliably feeding BBs, so rather than spraying BBs everywhere it only sprayed two, then jammed.

I think with some modding this could be good. File down some plastic, maybe fill in some space, and it might feed more reliably. But if you're going to have to mod it anyway, buy two $15 Matrix mags and use them instead, then buy yourself a nice sandwich with the leftover $10.

TL;DR: Mag doesn't feed, and mine showed up broken. I'd give it a 0/5 if I could.
