1) The rubber/plastic seal for the glazing had twists in it caused by the handling and rolling up, it should have been on a spool so it could be unrolled straight and without twists, it slowed down the fitting by quite a time period as well as being very annoying, of the 64m i don't think i had half a metre that went on as it should. 2) I couldn't get the glass out of the pallet it was in, on removing the removable batons all the glass packs wanted to fall out. 3) I didn't get a list of what was in each pack of glass and it was in the rain so i had to mark the packs with a number and make a list of what was in each as the little sticky on the packs was falling off. 4) There is 2 x 15mm screws fitted into the rear gable instead of 10mm and never found out what they are for, they only showed on 1 set of instructions. 5) The delivered instructions and the online instructions are both needed as one has pictures which can be hard t see and the other has drawings which are easier, the items in each are marked different as one uses the alphabet and the other numerals, confusing. 6) I am happy with the greenhouse now it is errected, but a pain when you are erecting it on your own.
