Built it and it seems very flimsy.  I could not attach it to the side of my house with the brackets they gave me. I did pour 1/2 a bag of pea gravel in each leg to give them weight to help it out. (FYI you need to do this before you put the top panels on.) The top panel are not as solid as I like them to be but at least it will be easy to replace them when they get hail holes in them.
