My controller is excellent for the price. Input lag isn't noticeable, sticks feel fine, all the primary features are good. The other extra features is where it gets problematic. Maybe it's just my unit, but the rumble motors whine whenever they're in operation, pretty obnoxiously to the point where I can't use rumble at all without straining my ears. The RGB is pretty bright and it takes a few button presses to get them to turn off, and for some reason the controllers entirely turn off for a few seconds? They also don't seem to remember my previous settings, so I have to turn off the RGB and rumble over and over. These cost less than Nintendo's official product by about $10-15, and for the extra features it has I think it's a fair deal. However, DOYOKY may need to spend more time on their Quality Control.
