The product itself is brilliant (once up) - it slots into a compact space and works really well.  The problem is in the mounting of it on the wall.  The designers themselves have clearly never tried putting it up themselves.  It's unnecessarily awkward and very time consuming.  If the screw holes were on the outside of the bracket it would be have been so easy but instead the designers have tried to conceal the screw holes - as if it matters if you see a screw on a washing line!!
