Pros:
Its very cheap
you just have connect the usb in your wii and you can start charging!
it has nice red colour when its charging and when its fully charged it turns in blue.
you can also connect it on your pc/laptop to use it for charging :D
Cons:
- must take off the Silicon case on the wii remote to charge (annoying) and have to get the strap off too if you want to charge it properly..
- charging is pretty slow...
Bottomline:
It works GREAT if you have a WII, i recommen you to buy it, its better then buying batteries and replacing them all the time
