We have had 2 of them. The 1st one ended up in our swimming pool because it wasn't tied down ( wife told me this). The 2nd one was tied down with 6' rebar and cork screws. It flew threw the air in a storm and 1 post came a foot and a half into are closet. The rebar and cork screw still attached (guess the wife was wrong). Don't tell her I said that LOL. I told her if we do another it will be buried underground. Look them up they are actually pretty cool. Just my 2 cents.
