Super easy to pop open.  Like others have said, a bit more challenging to put away, but after watching the you-tube video, it was easy.  Watch the asian guy with the orange tent....he goes the slowest so you can really see how to do it.  I am 5'7" can can sit inside with plenty of head clearance.  It is long enough were 3 people could sit comfortably.  We plan on taking it to the beach.  There are no sand pockets, but I am planning to take a couple of zip-lock bags to fill with sand to anchor it down.  Overall, I think it will be just what we need.
