Pros: Looks good, "pop-up" isn't as easy as it sounds, "heavy-duty" is a term I wouldn't use, more "medium duty" but with that said, it works well. The velcro ties are attached to each part of the tent. the top to hold in place and to each "window" or "zippered" side. Con: the edges where the velcro attaches to the window or zipper sides needs to be thicker, I can see wear  and fraying of the edges already.
