picture shows 2 units back to back - that is not what you get. Assembly was very confusing - orientation of parts is not clear from the diagrams.instructions. Would not purchase again

This cold frame had some issues when it arrived. There was on piece of aluminum that I had to bring into the store so it could be cut about half an inch shorter so I could finish assembling it. In order to use the top pieces to cover the cold frame at night they must be attached just so. The hinge joint is extremely weak, which is why the directions are full of warmings about leaving it open in the wind. The design is actually quite clever, but if the base is not perfectly square when you attach it to the ground beneath it, the top pieces will not fit. It is very easy to get it out of alignment, even though there are little corner pieces at the inner joints that should keep everything at right angles. they don't quite succeed. It took a long time to assemble because all the directions are in little pictures, and nowhere does it make it clear how to find the piece you need for each side. For me it was a process of trial and a lot of error, but finally I figured it all out.

Very flimsy not worth the money would not buy again made with cheap aluminum and plastic parts hopefully it will last a year

Be aware that the instructions are in German. There are photos of the process, but you will be so irritated by the second step, you'll want to return it. I went to the product website and there are NO English instructions.
