knows how, the place where you insert it into the Wii was cheap plastic and all I could see were exposed wires

Cheap plastic.

This power box came in the mail in a plastic sleeve, a bit sceptical when i first opened it

Retun policy was to use original packaging--a flimsy plastic bag that was unusable after being opened.

Works as it should.

It does not feel as solidly constructed as the original, but works as it should.
