the product itself, however, is functional but kind of strange. it has two spaces for a wii remote, and when you put one remote in it starts charging right away (the blue light turns red, to show that it is charging) but when you put the second remote, sometimes the second light turns purple but it charges just fine anyway (maybe it is the blue and red lights going on at the same time, which is harmless, I'm not sure and didn't bother with it because it works just fine). Also please note that the wii must be turned on for this charger to work, it takes it's power from the wii itself because there is no wire that connects it to the outlet in the wall or anything. just leave the unused remotes plugged in while you play and it should charge just fine.
this charger connects to the wii from a USB port, so if you have a HDD connected to host your games like i did, and you're planning to buy two of this charger for all 4 wiimotes, you should remember to buy a USB hub with several USB outlets because the wii only has 2 USB ports on the back XD
I am very happy with this product, this was my first purchase from lightinthebox and I'm sure i will be coming here again!
