I have one. I've shot a few thousand rounds through it and haven't cleaned it yet.

Still works good, still accurate. I like it, not practical though, just a real fun plinker. If I didn't have the cash to spend, I would get a 10/22, simply because you can hunt more with it (IMO). But if you like shooting hundreds of rounds, the GSG really fills that void. I see it as a money saver. Hope that helps.
