To reduce any risk of getting a counterfeit product, I chose from the sellers list "Amazon's Jersey Merchant" (i.e. Indigo Starfish) at £9.99. I have received an absolutely genuine Nintendo Wii boxed nunchuck controller, that is utterly identical to the one supplied with my Wii Sports Resort bundle, right down to the tiny code numbers stamped into the plastic near the wire outlet. The box and packaging is typically over-the-top Wii, with stiff corrugated cardboard and separate protective bags on the cable, the controller and the connector! That lot must have cost at least £1.00 of the purchase price! No worries.
