If it is hot-swappable you see on Banggood or Amaz, then it is the same keyboard, the V2 here stands nothing.
$60 for a hot swap keyboard that looks this good, is worth it.
By the way, I recommend this keyboard. Just received one from somewhere else, for the same price. Buying it here gives you better warranty service and will support Drop.
Yeah, the Astrolokeys will fit. One thing to note, though, is that the Astrolokeys Windows/System key is 1.25u and it looks like this keyboard has a 1u Windows/System key and 1u function key. In theory, this should not a problem (however personal preference may dictate otherwise) because the base kit of Astrolokeys has enough 1u keycaps left over to cover this 66 board (eg. insert, pgup, pgdn) with keycaps to spare for use on the system and function switches. Since the DSA profile is flat sculpt you can move the keys freely without worrying about the sculpt profile of the board.
