This canopy is great.  I love that I can leave the side open, add only the walls I need, or enclose it completely.  Its pretty easy to set up, but you do need two people.  The sandbags were a great 'bonus'.  It helps so I don't have to take it down on windy days.  I haven't transported it anywhere yet, but it packs up small enough to transport easily and has a very nice carrying case.  I am happy with this purchase.
