Great little greenhouse. I was skeptical when I opened the box and saw how thin the panels are: I was imagining something like plexiglas, and these are more like the plastic boxes berries come in. Once it's assembled, they look fine and it seems sturdy enough. I'm already wishing I had bought a larger one.

Assembly took about 6 or 8 hours. I worked alone for about half that time, but for some steps, a second person is necessary. We went very slowly with the instructions to make sure we were reading them right. There are only pictures, and those pictures don't usually indicate whether what you're looking at is the inside or the outside. We spent a good bit of time flipping pieces back and forth, trying to visualize how it was supposed to be oriented. There were a couple of times when we had to go back two or three steps to take something back off and flip it around.
