I put one of these together for a friend yesterday. It’s honestly a very solid product.
As IO Sam pointed out, while the gaskets don’t do much for flex, they do a great job at sound and vibration dampening.
This is also one of the few mid-range hot-swaps I’d actually recommend as a tester board: the plate’s grip is on the loose side of normal - so switches aren’t going to get stuck in there like with the NK65, and unlike most of its peers, the hotswap sockets are physically supported when the keeb is assembled, so it’s not really necessary to break the whole keeb down for the sake of care when installing new switches.
The caveat here is that the board has so much dampening, you might not get as much of the character of a given switch as obviously as you would with something like a GK. On the other hand, the Pro has a solidness and tightness that a GK likely never could.
Holy jeez the screws were tight, though - and while I’m sure the stabs are plenty tunable, the lube that comes on them is a little bit too much like glue, and there’s lots of it. I learned that it’s not enough to simply wipe the stuff off those little pads - you gotta squeeze it out if you don’t want it making your keys tacky after assembly.
