Super value for the size. 
Quality is very durable . the parts are precise 
Instructions are pretty clear. Just follow the steps dont skip any steps 
make sure you angle the bars for the two front walls correctly or the screws wont line up . 
Set it up in 3 days time though im sure it can be done in 2 if not one day with help if youre dedicated enough. Im very satisfied with the purchase over all . 
Delivery time was extremely fast. 2 days from purchase date it was at my door step.
Enjoy fellow Greenhouse owners.
