I am aware of the return policy but just to be on the safe side, let me ask: do you know if I can return one switch after I test it and, for some reason, it does not work as expected?
EDIT I just realized they do not ship to Japan in the first place. That’s it. I am out.
Thank you for the feedback anyway. I hope that one day they are going to make a switch that can be used outside of North America.
