It's made by Eightarc, the company that makes the Qanba line. However, Qanbas are notable for the Q4 series, which are dual modded and have Sanwa parts (read: good stuff, also found in Madcatz TEs), whereas the Injustice stick works on only one console and uses Qanba levers and buttons as found in their non-Q4 sticks. I've used a Q2 Glow before, and while the parts weren't terrible (I could still do combos and such), they felt noticeably different from Sanwas - the stick had an odd creak to it and the buttons were far more resistant (and squeaky) than Sanwas. You could always mod it, but since the mounting plate for the lever apparently doesn't match that of Sanwas, it sounds like it'd be more effort (and cost) than it's worth.
The injustice stick is not made by Eightarc it is made by PDP. I own this arcade sticks along with few other madcatz TE sticks and compared to the madcatz (TE,TE-S,VS,PRO) sticks the madcatz is a better choice. Ive personally never used a Qanba or Eightarc stick but i hear they're great sticks also. Ill give some pros and cons about the injustice stick and hopefully it could help some. Ill say if you either collect arcade sticks or new to arcade sticks get this stick. Also if you dont already have the game its a plus and if you do have the game sell it for a little extra money back.
Pros
* It is a great beginner stick especially at that now $60 price tag
* It lights up and looks cool of course.
* Its not hard to replace/swap buttons if you desire to, however the stick needs a plate mod if you're going to use a sanwa joystick. FYI if you get the stick and plan on modding it careful not to pinch the wires when putting the back plate back on it is easy to pinch the wires.
* The injustce arcade stick is better than a stock madcatz SE stick/ brawl stick. IMO
* Easy to swap artwork if desired to.
Cons
* The arcade stick weight is to light.
* Does not have rubber feet instead it has a seude like bottom that slides if sat on table top.
* The joystick feels too loose IMO compared to sanwa joysticks. The sanwa joysticks are a bit stiffer.
* This is a preference based but it comes with a bat top, It could be changed to a ball top but the shaft is to long. So you would have to change the shaft to make it shorter if you switch to a ball top.
* The buttons are to stiff and not as good compared to Sanwa buttons.
They're just a few break downs. Now every one has their own opinions on the arcade stick. But Hope i helped a little for anyone thinking about getting the arcade stick. ohhhh and also yes the arcade stick does work for other fighting games not only injustice.
