Korg MicroKey Air with Windows computer?

Trying to improve my music production ergonomics, I have become interested in wireless MIDI keyboards lately.

Since I use Windows, it seems as if Korg MicroKey Air is the only feasible alternative. There is not a lot of information on the internet, but I have seen a few comments and mini reviews and the users overall seem pretty happy with it. I miss information about latency though. Korg states that their solution gives low latency, but I have not seen any real milliseconds facts…

Is there anyone in this forum that uses MicroKey Air with Windows that can comment further? Are you happy with it? Is the latency low enough to record anything you want in realtime?
