I too was "hooked" on them. Seemingly THE perfect thing for ejection charges especially, but great in many other applications. Bought them by the gross when they used to be available (and at a great price!). And then.......the whole "hard to get"/"backordered"/"not available" thing began, sure enough just as my own stash was dwindling.
So like many others, I started using ematches more and more. And luckily, many sources of inexpensive (but reliable) ematches (sometimes now called "starters") started showing up. So I started stocking up ematches in bulk, and pretty much used them exclusively for ejection charges and whatnot. And you know what?....they work great, are easy and cheap to get, and I'm perfectly content.
Q2G2s have now faded away into the past as far as I'm concerned. It was great while it lasted, but there are perfectly good alternatives now and I've "broken my habit" for them. If Q2G2s suddently became readily available again, AND I could by a dozen dozen of them for cheap, then yeah I'd probably get and use a bunch. But if not, I honestly don't really care any more. Life goes on, rockets get flown, and they've been left behind.
