Leopold FC660M PD

Leopold's FC660M PD is a 66-key layout that keeps a dedicated arrow cluster and two extra navigation keys in a footprint close to a 60% board. Leopold sells it with a choice of Cherry MX switches; Tech Critter lists seven (Red, Brown, Black, Blue, Silent Red, Silver and Clear) and describes the keycaps as 1.5 mm double-shot PBT. Leopold's own product page shows the specification sheet as images, so the details here come from the reviews: a conventional case with a top cover, Cherry-style stabilizers, padding between the back plate and PCB, a detachable USB Mini-B cable and rubber feet with a kickstand.

Tech Critter, whose review unit had Cherry MX Browns, found the build excellent and the stabilizers more stable than on similar boards, which it guessed were factory pre-lubed, and called the keycaps the fanciest stock set it had seen on a mass-produced keyboard. Its cons were the mini-USB port and the cost. Techtesters scored it 9 out of 10 on a Cherry MX Blue unit, calling it rock-solid with neat PBT caps, a damping layer and Cherry stabilizers; it found the Blues loud and wanted USB-C, an English manual and feet that did not collapse so easily. The 66-key layout changes the left Windows key and right Shift, so standard custom keycap sets will not fit, as Tech Critter noted.

It has no hot-swap sockets, backlight or software.
