These Shelter's are perfect for giving shelter to your equines, sheep, goats, etc. Those who claim they need 4 people, I beg to differ, I built the two I bought by myself and had no other help. It isn't that hard if you know what your are doing. The only thing I did not like is the shelter canopy itself last for maybe 2 season's before it starts getting some tears or holes in it; however, where I live we do get strong winds and 100+ degree weather most days of the summer which really damages all kinds of fabric out in those conditions. But it ships with thinner canopy's and you can order thicker ones in the future when you have to replace the canopy cover, the thicker canopy has been on for 3 seasons now with a little tearing on one. The manufacturer is great about dealing with any issues when it is shipped to you. One was missing parts, the end was ripped open and taped shut from shipping, thanks Fedex for caring for the box. This isn't the fault of the manufacturer, and they had me the replacement parts in 3 days. The tearing you see in the above photos from one reviewer is them making the straps too tight when you anchor the canopy to the frame. For some reason people think you can ratchet clamp these down as much as you want and the fabric wont tear, when it will in fact tear if too tight. Basically easy to build if you use common sense and are handy. I am ordering our third one today or tomorrow since they are so easy to build and use, and work really well for sheltering the animals. All in all a great product.
