3rd Party Nunchuck no longer recognized by Wii?

I bought a third party Wii Nunchuck (I know, big mistake) and it didn't even last for 60 days. I ended up trading it in to Gamestop (if you tell them it is broken, they will still accept it, they just pay a little less) but afterward thought, gee, that was dumb, I should've tried to repair it first - those things are expensive! For others out there experiencing the same problem, does anyone have a repair solution? With my Nunchuck, one day the Wii just stopped recognizing it. I tried resetting the system, the controller, plugging and unplugging numerous times, but no matter what I did the Wii could not see the Nunchuck.
