Everyone mentions breaking, but I tell you what, if they just copy the official one, they can't go wrong. Playing a bit of baseball on my wii the other day with my friend, we had a few bottles of Koppaberg, this Swedish Cider, and while pitching, my wiimote took the neck and head of a bottle clean off. Clean off! No spillage at all. The remote is still perfect. Bear in mind, they are 500ml bottles, with a fat neck.
