Some people have mentioned quality control issues with this keyboard vendor, particularly with the Model F. I have the Model F and it is a bit finicky admittedly. I support the vendor based on their hard work to bring back these classic keyboard mechanisms, but if you want one that "just works" the Model M from Unisys is probably a better bet.

As far as the beam spring goes, this is the second revision of these switches. These switches are a complete modern re-imagination of the original beam spring switches and support Cherry-style key caps. Unlike the Model F, the switches are self-contained and setup just involved putting key-caps on. The keyboard worked flawlessly and immediately.

This is an enthusiast trying to bring back classic keyboard switches that have been out of production for decades, so I am willing to grant him some slack in general, but I'm extremely happy with my board. It's a very different typing experience, but I love it. I understand many people aren't willing to risk $400 on a keyboard, but I also want to let people know about my great experience with it.
