I am SO happy with my porch enclosure system that my son installed once I received them in the mail. They are easy to use and I have operated them all , all by myself, and I’m 75 yrs old. Right now they are down for the winter storms and I’m thrilled NOT to have flimsy plastic blowing all over on windy days (in-spite of the thousand staples) like last year. I highly recommend the PPS and I hope to write another review after they’ve been up in the years to come. You’re welcome to see my photos … with and without (before & after) the PPS. I wish I could show you the video I have during a storm.
