The only good thing about this product is the frame is very durable. The down side is when the holes don't line up you have a decent amount of metal to hog out to make fit. Every post required one person to move around while the other beat on the bolt with a rubber mallet. That is also assuming they sent you the correct parts. For this they sent the wrong ends. Went through the shelter logic customer support to get the correct ones and one of the two replacements they sent had a hole. When setting up the ends you have to be very careful to get the tension just right as to tight will prevent the doors from zipping closed and too loose will make you have to use two hands, one to hold the track and the other on the zipper. On a finale note the quality of the fabric is exceptionally low. When you stand inside you can see thin spots in the canvas that will be holes in the near future. If it wouldn't be such a pain to tear down I would return and get my money back.

we love this product it is a very durable structure and fit our needs here on the farm
