Q: First, this thing is HEAVY! Once I got all the measurements made for the installation and before I drilled any holes, I opened the board to full extension. I found that no matter what I did, I could not get the board to remain flat and rigid. The board folds in half, then folds again to the wall. The hinge in the middle of the board was ineffective in keeping the board flat when fully extended. As a result, the board would be rigid and level from the wall to the middle hinge, but the half of the board beyond the hinge would flop loosely with about two inches of flex. It would be impossible to use the board. I do not know whether the problem was unique to the board I got, but I was unwilling to try another and returned the product.
A:
negative
