Positives were good delivery, driver phoned before and off loaded greenhouse boxes into garage. Erecting the greenhouse myself (apart from assembling the ends and side together) it took 2 1/2 to 3 weekends in November. Weather wasn't great rained the first & cold the second two plus lack of day light limited progress. Instructions covered everything though would have been better with more pictures. However the on-line video helped when doubt arose. All the parts were present. One aluminium piece was slightly damaged in an area. It was easily straightened with a pair of pliers and then fitted ok. Be careful with the screws there weren't any spares (though excess of nuts). Excess of glass panels which was good in case you have a little accident, which I didn't so I've got spares for the future Greenhouse now installed screwed to paving slabs and has survived the first storms of winter. Overall it looks a really good buy.
