Redragon K585 DITI RGB USB Mechanical Gaming Keyboard
MSRP $54.99

This is an open box item.  I have tested the keyboard and the macros, and it does work perfectly.  When you configure it, you should use their software, rather than doing it directly on the keypad.  There's a note in the box saying the same, with the link.

If the keyboard does not respond, plug it into another USB port on your computer.  I had problems with it through a USB hub.
