When we got the delivery we were skeptical because of the contents. The directions were in picture form instead of written and the poles were thinner than expected. We were surprised at the ease of putting it together. Three people were needed when the crossbars were put on the frame. The hardest part was placing the vent top over the frame! It looks great. We haven't had a rain storm yet, so can't comment on waterproof or stability issues. We anchored it to our deck. It seems to be a good purchase!
