I really like it. The switches aren't that bad; Or, at least, not as bad as some reviews have made it out to be. The typing experience is very pleasant. The build quality is lovely. And, my primary motivation for the purchase, it's great having all the benefits of a USB 3.1 dock! With the Launch Heavy I suddenly now have 5 unoccupied USB ports to utilize (not including the 2 occupied on the back of my miniPC and the 2 occupied on the keyboard itself)!
Probably the only thing I would like to change would be the keycaps themselves. They feel good, made out of high quality PBT plastic...but, my fingers simply aren't used to this profile of keyboard. I believe the Launch Heavy uses XDA profile, which I'm not used to. My fingers are hunting for an OEM or TaiHao profile. In fact, in the past, I've even considered an SA profile.
All that said, it's still a great keyboard. Extremely solid. I'm very happy to have a 100% keyboard layout now, plus the USB hub. And, all in a very beautiful, tactile, functional package!
