Kinda feels like a really heavy Topre board. Jwaz once described it as 65g Topre.
I agree, except for the space bar, which is horrible.
Wish they had used reds instead of blacks, though. Combined with the rubber seal, it would probably have felt really nice, other than the form factor.
If you get it, be careful taking it apart if you want to use the touch pad, the connector is really easy to pull out.
