After reading reviews about dpad left often registering as up, I was extremely hesitant to buy, but decided to take a chance, hoping these were one-off anomalies. Received and almost immediately noticed the dpad issue. Tested extensively against my OEM controller and it's not even close. It is practically impossible to push left on an OEM controller and have it register as up, even if you are applying pressure upward. Do the same thing on this controller and if you apply even the slightest bit of pressure even slightly upward off dead center, it registers as up. For an analogy, think of an arcade stick and square versus octagonal gates. It's as if the original OEM controller pad was designed with square gates, all the games were meant to be played with a square gated controller, and this controller decided to use octagonal gates. But instead of diagonal-up-left (and by that, I mean like even 1 degree above horizontal) registering as diagonal-up-left, it registers as a direct up press. It's actually very screwed up and obviously a poor manufacturing design flaw that unfortunately hasn't been and probably won't be addressed. Which is a shame because everything else about this controller (cord length, form factor, design, weight, etc.) is really likeable.
By the way, if you have this controller and an ED cart, easy way to test. With OEM controller, go to the menu and hold dpad left and observe the scrolling behavior (you'll change pages, but not overall position per page). Now do the same thing with this controller. Not only will you change pages, but you will occasionally notice your position on the screen moving upward (indicating upward dpad registers). Try this a few times back and forth between controllers and you will see just how different these controllers are.
