I like the materials a lot. I've been working with the patboard Kanban to organize our project team's tasks. We work partly with Lean/Agile/Scrum methods, we used to work with post-its but they tend to fall of the wall all the time. So this is solved with the patboard magnetic cards. I've had the pleasure to experiment with the adhesive (non magnetic) edition as well. They work impressively well on the glass walls and windows as well. So if you don't have magnetic boards, use the adhesive edition, they last very long (haven't failed us yet). So thubs up for patboard ;-)
