Overall I am delighted with our pop up screen tent.  Spacious and airy, frame is substantial and sturdy.  The zippers are of good quality and large enough to do the job well.  
There are a couple of things I would change if I could.  The corners of the overhang are supported by pieces of metal which easily pop in place.  They do the job well but being separate they could easily be lost or misplaced.  The screen is attached with clip on loops which thread through a length of twine that is secured behind the corner posts.   Simply not convenient for putting up and taking down numerous times.
