I bought this about a month ago after researching greenhouses for several weeks.  I liked this one because of the price and reviews.  I LOVE it.  It looks great and the quality is better than I expected.  It was also much easier to assemble than I expected after reading reviews.  It's not as hard as folks make it sound.  At first I was unimpressed with the polycarbonate "glass" panels (they look like etched glass, but feel like bubble wrap material), but now after its been out through good and bad weather, it held up very nicely.When I got to the end, I found that I was missing a small part (roof panel separator) which I probably misplaced in my messy garage.  I emailed Aosom, and they responded WITHIN 1 HOUR!  They offered to send it by FED-EX for FREE!  I was really impressed.I RARELY (if ever) write reviews, but their customer support won me over.  They deserve a special shout out for being so responsive and helpful.
