I bought four of these to create a raised bed garden protected from critters and at a back saving height. There was so much plastic to peel off the panels, that took at least 20 minutes for 2 people for one set. The plastic film was folded under the edge of the metal, making it near impossible to completely remove. Putting each one together took 2 people and between 45-75 minutes. I don’t know how long or if it would even be possible to do alone. 
One of the sets arrived with some bent and dinged panels, probably during transit. Be careful when unboxing you avoid scraping. The finish or gouging your hands. 
They look good when put together, and much sturdier than i thought they would be. I would probably buy more of them, maybe not in this size.
