I heard those cloned Nintendo 64 controllers are complete junk. I personally would NEVER buy this type. If you want an off-brand controller, get RetroBit's Nintendo 64 controller. It's a little harder to use than Nintendo's original controller due to the fact the deadzone is a bit big on this controller, but aside from that, it works pretty damn well. Here's the controller in question:

That's the RetroBit controller I have and I really like it. Some actually have PlayStation-style caps on the analog stick, complete with a very nice textured rubber top(mine is like that). If it was up to me, I wouldn't use any official Nintendo 64 controllers due to them wearing out(I only have one official Nintendo 64 controller with a tight analog stick and I don't even use that because I want to keep the analog stick tight, and yes, I have lubricated all the plastic parts in the stick) unless the analog stick has been replaced by this type:

Only then will I consider using an official Nintendo 64 controller. Until then, I'll stick to my RetroBit Nintendo 64 controller(and my Tomee Nintendo 64 controller so I get used to that thing's oversensitive analog stick - seriously, that thing has an even bigger deadzone than the RetroBit controller and on top of that, it reaches maximum input before you actually push the stick all the way!).
