See my sibling comment: the v2 beam spring keyboard (metal version) worked immediately out of the box and all I had to do was but key caps on.

This is an enthusiast producing these and the beam spring mechanism is entirely redone with modern touches (e.g. support for mx style keycaps) so there is risk, but mine works great. I think that the fully enclosed beam spring mechanism should hold up better during shipping than the spring-and-barrel mechanism on the model F.

Of course YMMV and it is an expensive and rare keyboard, but my experience has been good.
