Looks sick, was just looking at these keys today for my new gmmk Pro. >

Cheers, They're nice. Really happy with them. Video doesn't really do it justice. 
Main issue I had with the ISO board is that I needed to order the 'addon keys'. Bit of a pain as they weren't available in the UK so I had to import them from Spain. 
The base pack was missing the smaller right shift key (can just about get away with using the 'tab galaxy key' as an alternative) and the bottom right Alt, Function and Ctrl keys.
Just something to bear in mind.
