I got this greenhouse when it was on sale and so far it has held up to super high winds over the last week.  I keep crossing my fingers it will still be there the next morning, but so far, so good.  My son put it together and did not seem to have any issues.  Kind of like putting together a tinker toy set for the frame.  We did zip tie each of the shelves to the shelf frame in 2 places.  I think that is a necessity.  The clips don’t seem strong enough.  I am just using it to store tools and extra pots etc. to keep them out of the rain.  I don’t plan on putting any plants in there because they will roast here in Southern California since it was 85 degrees last week in January!  I am happy I purchased it and hope it stays in one piece with the weird storms we have this week.
