We love it! Great starter greenhouse. 
We were surprised at how good it is and how easily it went together. Highly recommended!

Directions are pretty vague, but it’s smooth sailing once you figure out the orientation of the intersecting corner poles. 
The enclosed small open end wrench and allen wrench are fine, however, I would recommend using a 10mm socket, instead of the small wrench for faster assembly. 

The instructions suggest not tightening the nuts and bolts, until the frame is completely assembled. 

The roof will go on with one person. I recommend two people.
