Impressed. 
Clear instructions. Straightforward to make by single person. Heavy when arrived in its packing but surprisingly easy to lift and position when constructed. Looks good and the range of differing shelves  heights makes it a versatile shelving unit. 

The only criticism was with the webbing supplied to anchor the unit to the wall. I fitted it as directed but the unit was not as secure as I’d expected. It would prevent it falling but the unit did still tip forward - so I attached a metal L bracket to remedy that issue.
