Ran some tests on a lot of 5 controllers I got for 20$. Dante's first mission on DMD mode, to both utilize all buttons AND to stress test. Two out of the five controllers worked flawlessly. One was unresponsive. The other two freak out upon being activated. Slightly disappointed, but I can still call it a win cause I got two decent controllers for 10$ each. Gonna have to figure out if I wanna get the others repaired or not.
