I received my V80 today with the Matias Quiet Clicks!
Here's a moneyshot:
I replaced some keys with an incomplete set of thin ABS doubleshots I have from a butchered FK-2001. The stock keycaps are even thinner than the ones on the Focus's though they actually feel somewhat denser. I'm fond of the colored shift and escape key myself.
The build quality of the rest of the board is excellent though, it has a good amount of weight to it and doesn't flex at all. Furthermore the keyboard's finish is very slick matte black.
I really like these Matias, the tactility is stronger than I was expecting. I don't really care for the dampening though and I'll probably pop out the bumpers on the slider. The keycaps from the Focus give it a kind of neat sound I can't describe. They are really smooth and when I opened up a switch it felt like there was a very small amount of lubricant on the slider. Has Matias always done this?
The spacebar is also lovely, not rattly and doesn't sound much different than normal keys. The other stabilized keys are kind of rattly though.
Here's a close up of the keycaps, the Focus ones need a light wash and you can see some nicks too, scars of the past!
Overall I'm happy with this board and would gladly recommend it and it's switches to anyone.
