Yeah that makes sense, especially from what I've read on a few different places about the Vaxee mice causing some pros to use them wired at tournaments!Those features sound bloody useful. I just run 2k polling all the time. I think Vaxee mice were having problems at esport events due to wireless interference, which is why they went with a beast of a dongle. Pad looks great too.
I actually don't mind the larger dongle in reality, it means it doesn't awkwardly balance not quite flat at the edge of the desk too.
