I have one of these. It's incredibly solid, and the typing action is light and snappy, just like the originals.

How is the noise level when typing?

I have an original Model M, and it feels great, but a bit too noisy, e.g. I hear the clicks even when in noise-cancelling headphones.

It's clacky if you bottom out heavily, and twangy even if you don't.

The sharpness of the clacks makes noise-cancelling headphones not work so well on it.

It’s at least as loud as my original Model M.

Edit: I have one of the new Model F keyboards, too.
