I got this for my 20' heavy duty tunnel and it's everything it claims to be. SO much easier to move my tunnel with this instead of dragging it across the yard - omg. I didn't think I'd care about the storage factor, but I find that I really like that too. Nice and tidy and compact - all I need to do is wheel it where I want it. In fact I like it so much I'm ordering another one today for my 15' tunnel, which is also heavy duty.
