Have a handful of Jorgy CMs, got them really cheap from an Ace Hardware internet buy about 3 years ago. Like them quite a bit, haven't had much of an issue with them. Occasionally the head jams closed, but that's usually if I'm silly enough to let the heads meet with nothing between them and the screw is mostly out. When the...cross bar?...whatever you call the thing the screw goes through...when it is jammed forward and there's no way to move the head forward to release it, it's tough to separate the heads, but that's a pretty rare problem for me. Once I figured out what the problem was, I've never seen it happen again.
Used 8 for an ATC build last year and was very pleased with the experience.
Just my $0.02.

Not all chemicals are bad. Without hydrogen or oxygen, for example, there would be no way to make water, a vital ingredient in beer.
