The build quality of the components for the greenhouse is excellent, and delivery was good. Customer Services were always responsive to enquiries. I am very satisfied with the finished product. However, the materials quality is not matched by the quality of the instructions, which are messy and poorly thought out, with multiple instruction sheets to cover the various permutations of size, configuration etc. For this reason I rate this only 6/10, as there is obvious room for improvement and with a small investment far better instructions tailored to the individual product could be produced.
