The quality of the greenhouse structure is generally good. Delivery took 3 weeks which was a little disappointing for the spring when you want to get on with planting etc. The quality of the pictures in the instruction book was poor in places especially for the window. The holes to fit the automatic window opener were not big enough on one part of the frame so had to take it to pieces twice! The quality of the louvre opener is very poor, not sure how long it will last. The look of the finished greenhouse is good. We are pleased. Just those few niggles above would have made it far easier.
