I bought it on etsy.com after last Christmas and right now I fill very comfortable. First several months I played with configuration and different layouts and learn blind typing as well. My final config could be found here. The base layout is Colemak-dh, second one is for numbers and arrows. Third one is for special characters and final layout for mouse movements. It is vial compatible and I use macros, combos and tap dancing intensively. Also I use modifiers as holding keys, but above home row, as it speed up my taping and I produce less errors.
