I've bought the set a year ago on ebay, initially has all worked out, after a short time but I have noticed that the Nunchuck responding too sensitively. The smallest movements were often registered as a shaking, which was really unbearable in games like Super Mario Galaxy or Zelda. I then turned me to the support of the manufacturer, without success, but the dealer on ebay was maybe not very cooperative, as it would look like here I do not know.
After a few months of the Nunchuck went completely broken, and the remote control has its mind now also abandoned and it was definitely not dead battery, or something like that, it just does nothing with completely new ones, no reaction at each button. I have been doing the controllers neither frequently used even mistreated, but this was only for the second player, but when I tried the other day using the remote control again, she was suddenly broken.
Conclusion: Considering that the kit has held only six months, but then rather expensive.
I therefore recommend that the handle to the original, which runs smoothly for over 3 years and I do not know anyone with whom she has given up the ghost.
