108 keys, seem like the bottom row has the standard 1.25u keys with a 6.25u spacebar.

Are you planning to replace the keycaps on your ducky?

Wouldn't you be missing some R1 keys and have to use your old keycaps for the 4 keys on top of numpad?

I would suggest to look at other brand, like Leobog or Aula, They give more for way less money. there is well wrriten review in this tered u may read on Aula F99 board. At Post#1534
