I'm negative on the koala. I bought one as a 'soon to be retired' present to self. I really liked using it, but we moved and although I always kept in in the house (my bedroom, so it was heated - it was not left in damp or severe heat) When I started using it again I found out that all of the rounded edges were delaminating. I take responsibility for the lift mechanism failing, my son didn't see the instruction before he put the top down. But delamination REALLY this was a top of the kind purchase
