Review on SIBIONO - Wireless Bluetooth Dual Analog Joystick: Enhance Your Gaming Experience with Nintendo Wii U Pro Controller Gamepad by Eric Stewart

So for starters it mostly works as intended. The battery life seems good, the buttons are mostly responsive with a success rate of about 99%. However, if I didn't have a dedicated set of screwdrivers, I would have to return this controller. Right out of the box, that right controller trigger was finicky. . After a bit of research, which involved disassembling the controller, I noticed that the right bumper and trigger button component were very loose. After a little maneuvering of the internal components, the trigger works much better. It doesn't seem to respond when the game loads, I have to wait a bit before it lets me continue. I do not know why. Other controllers don't have this problem. Not a game changer, but seriously, I have no idea what's causing this. If SIBIONO changes this product to say "Some assembly required" I will consider upgrading the rating until then. A star.
