We installed ours last summer, incredibly easy, maybe 20 min the first time. I took it off for the winter (though it is considered 4 seasons and you do not have to) and the reinstall this past spring took 10 min. Definitely not an involved or hard installation and worth it. THe freedom panels are great, but they are big and bulky to store. Now we flip two switches and in under 5 seconds, FREEDOM!
