This thing is awesome. My 3 year old uses the double line board and I switch it to one line. My 5 year old will use the two line pretty easily and is challenged by the one line. Nice addition to keep them busy and it beats having a slack line up in the yard, although I’m sure I’ll get to that point soon. I also stand on this at my desk, great way to get me through long conference calls about having a cover sheet on your TPS reports.
