Leopold says it launched the 660 layout in 2013, and the FC660M is the Cherry MX board built on it. You get 66 keys with dedicated arrows plus Insert and Delete, in a case about 33 cm wide that weighs around 700 g. The detachable cable uses a Mini-USB plug from Hirose, which Leopold picked for durability, and a red LED shows Caps Lock. Recent editions have Leopold's 1.5 mm doubleshot PBT caps, either in Leopold's PD profile or the taller OE profile, and Mechanical Keyboards sold a Vapor colorway with Cherry-profile caps. Switch options have included Blue, Brown, Red, Black, Silent Red and Clear. It shares its case with the Topre FC660C and its layout with the Bluetooth FC660MBT, so the letters after 660 matter more than the photo. Leopold also puts a hologram sticker on the back as proof that it's a genuine Leopold.

Versions
The FC660C uses the same case and layout with Topre switches, and the FC660MBT is the Bluetooth version with a USB-C port. Current wired editions are PD, with Leopold's low-profile doubleshot PBT caps, and OE, with OEM-profile caps. The Vapor edition sold by Mechanical Keyboards has Cherry-profile doubleshot PBT caps.
Leopold warns that its wire stabilizers can feel slightly mushy or scratchy and that switch springs can ping. The detachable Mini-USB cable is easy to lose, though any Mini-USB data cable fits.

Buying guide
Only five FC660Ms are listed, so the $160–340 band isn't a market read. We'd buy the FC660M PD titled with MX Silver switches at $83 delivered from a US seller, whose photo shows the box, the Mini-USB cable and the label underneath. The two new-stock boards ask $164 and $236 delivered, and the three used ones $83–435, including two red FC660MDS boards with Silent Red switches from Japan at $334 and $435. Read the label for FC660M, since the Topre FC660C and the Bluetooth FC660MBT share this case, and ask for a video tapping the space bar, Enter and Backspace for rattle, because the switches are soldered and a bad one means desoldering. Skip the $435 board, about 1.8 times the $236 median for what looks like the same red board as the $334 listing.

The lowest delivered FC660M by far at $83, a PD edition with doubleshot PBT caps and MX Silver switches as titled. Silver is a fast, light linear switch, so make sure that's what you want.
