[news] Ducky Pocket – Mechanical Numpad + Calculator(r/MechanicalKeyboards)
If you don’t care about Bluetooth I just bought this for $20
It’s definitely a generic blue switch -Outemu- but it works great. For $20 when I desperately needed a numpad for some extended data entry was totally worth it. Very solid, long usb cord, metal plate with plastic bottom, and very compact, without tons of extra plastic like some of the other numpads.
Only complaint is the slightly unusual layout with the tab button and small + key.
Also it does output numpad codes.
