At the end you could saw one in half!
Actually thinking about 'steamrolling' one of them ( the board that was most expensive and I like least : the celesta )
Got already some contacts trying to set-up a video creation event with a big roller ( the ones they use to flatten streets ). I'll give a keyboard the Mrinterface crush-award due to not meeting my keyboard quality standards and we can all enjoy how these bad keyboards come to a crushing end....
Fun ;-)
