There are some small issues with these shelters. Nothing some small thought can't figure out. I am a perfectionist so I made a 2x6 wood base for the shelter. I made it within half an inch of 12' x 24'. I screwed all the legs down to exact measurements. That doesn't work. This thing needs a little bit of flex. Eventually I unscrewed all the feet, assembled the unit and then screwed everything back down within an inch of where they should have been. What I learned is that is this is a big unit. Welding and sewing is not perfect on something this size. Within an inch is good. Overall, if you give or take an inch, it is a good unit. If you want perfection, it will cost you a lot more. As multiple reviews have stated, they give you a lot of string for the door openers. I completed both door openers with only the string from one of the packages. Now I have to figure out what I can do with the other bunch LOL.

Will build heavy-duty should last for awhile prints a little bit hard too read to the numbers on part's but once figured out went together verily easy and quick need more than one person

Excellent quality construction and durability. The directions are little tough to make out. Some description in the diagrams would go a long way.

Good over all size, but poor quality need for the manufacture to check items on occasion to make sure that the product is up to standard.. Needed to drill holes and round ends on a lot of pipe connection.
