I have car ports that are awesome.  Made with strong steel poles.  I thought this one would be of the same quality, yet with a great screened in option.  The posts are about a "dime" in diameter and made of plastic.  We just took it out yesterday to assemble for a dual birthday party for my two grand daughters (age 1 and 6).  Very disappointed.  I will be trying to see if I can fit the screen over my steel car port frame.
