Bought 2 from Lowes last year. My only major criticism is that the "shelves" are flimsy and unstable. I anchored them to the frame with plastic ties. I may replace the shelves this ;year with hardware cloth.
Also, part of the frame is plastic so you have to use gentle pressure when you fit the metal uprights into the plastic part. I damaged one part during assembly and had to shift it to the top of the structure.
They won't replace a real greenhouse, but they are good for light shelter while the weather is warming up.
