Rating : - Great if you hardly use it.
I bought this to play GC games and virtual console on my Wii. It worked great for about a week but then the Z and B buttons started to stick really bad. Also the A button is really, really loud. I didn't have any problems with battery life as it shuts itself off if you forget to turn it off yourself. Used it daily for about 6 months and had to replace the batteries about 4 times.
Both sticks were responsive and the d-pad is okay. D-pad has a weird shape and doesn't feel right though.

The Z button won't pop back up at all now so the controller is unusable. I took it apart to see what the issue was and it turns out that the plastic the external Z button is made of actually bent. The internal button also does not function at all anymore.

Descent controller for the money if you don't mind the ear shattering click of the A button and you're not going to use it a lot. Best for N64 games on VC but for Gamecube it just kinda sucks. Think I'll get a wavebird.
