I had one of these for 15 years until I bent a pole hitting it with the tractor. That was also about the limit before seams started to rot and come apart. With the domed top, it easily shed snow, we had one storm were we got almost 3 ft of snow with some pretty good winds on the coast of Maine.... no issues.

They are better made than the Shelter Logic units, also a little more expensive. I used the cable anchors that came with the unit. Waste of time, use the screw-in anchors. I needed to move my unit, I just made up a wooden frame that attached to the center of the top of the unit that mated with the bucket on my tractor. I lifted the unit with the tractor and had a person at each corner guiding it. Once lifted, it took about 5 minutes to move it about 1000ft.
