Size is great. Not sure about the different style of arms. We love the pull out kind. The hinged arms are a little awkward. It kept collapsing on our first set up. It took 2 people instead of just one with the medium size.
I love the product. I have sent numerous emails trying to communicate and have heard nothing back. It’s frustrating to me that then you want a good review.
It was much more difficult to set up than described. As soon as the wind blew, the top piece broke. Disappointing
