They are probably the best all around American style 8-way stick that you can still buy.
Agreed. They've got to be the most versatile stick I've used, I've never had a problem customizing them to get the feel I want. They're okay for 4-way, good for fighters, and great for everything else.
They're definitely Happ, the company they were purchased from only sells Happ products I'm told. I mean, it's possible they swapped them out, but even the paperwork that came with them was Happ, and all the other products (buttons, etc) are labeled SuzoHapp. Are the joysticks stamped somewhere? These aren't, so if the "real" Supers are, then perhaps they're fake.
I think this is why the discussion I've seen on this forum (and others) varies. Some people say they're incredible and have no diagonal issues, others say they're awful and best for 4-way usage. Even this thread is headed that way given the responses. Very strange.
Regarding how they're put together, I've tried every way possible, and still have issues with them. Oddly enough, out of the 4 I was given, one seems fine, two seem to work sometimes, and the last one barely at all. So it's quite erratic.
Meanwhile, the competitions I have in my own setup have zero issues, and work flawlessly.
