[Closed] Anyone use a Surf Key Box?

Been thinking about getting hold of one of these for a while. They make sense if there's a chance that a group will get split, or on an uplift day when the key would just have to staying in my pocket (and will possibly/likely get smashed in a crash).

Does anyone here use one, or know of any that are particularly good/bad?

This is what I'm talking about for anyone that doesn't know what I mean:
