I recommend 435

I'm tempted by this product because of the cheap price compared to products of the original brand.
I had 2 Wiimotes and nunchuks original but it took me 2 more for when my friends come to my teen (as they say, "While we are in front of the Wii, it is not in the street make c *** or to smoke b *** ").
And it works. Of course, we must synchronize the Wii:
1- Open the back of the wiimote, insert 2 LR6 + press the red button.
2- Close.
3- While the LEDs are flashing, press for 5 seconds on the red sync button on the Wii (under the valve protection of the SD card).
Be careful not to press more than 10 seconds, otherwise this button must resynchronize all Wiimotes!

If you have multiple Wiimotes, perform the same operation for each of them. Then turn them all and go to the Wii menu, go to remote and choose the order of wiimotes (4 max).

It's a breeze because I'm not very good at electronics and, if I can, anyone can do it!
