I have pledged on the €120 option which is not available anymore. If I want to add €130 for an extra keyboard, how will you keep track of the initial pledge that grants me the signature edition (thanks to the Hero)? With €250 (God, what am I doing? ) and the limited pledge I got, I should have a custom colour signed tohkbd2 and a custom colour tohkbd2, but I'm afraid you cannot see that once I change my pledge.
