Read about this a while back, looked so promising.
But I too am not too thrilled about the fixed hotswap. Mostly because well, if you want that, maxmill is the way to go, especially on a quality machined piece like this? Surely, it is bothersome to get placed on a board, but it is compatible with multiple layouts at least and is not as issue plagued as Kailh hotswaps (I'm assuming that is what is on here?).
I'm kind of wondering how the gaskets and all that extra foam works out. Really looking forward to seeing more. That said, given the price and interest so far, I have a feeling these will sell out of those 500 units pretty quickly.
