Just came back from using our new 15 x 15 pop up screen "house" over the long weekend!  It was awesome!   The sun shades are a MUST as well as the floor tarp.  The lights add just that little umph and we spent A LOT of time in it this past weekend, eating all of our meals in there and playing games into the night.  I would definitely recommend this shelter and we had 4 chairs and a 6 foot table and a 4 foot table in there along with 2 dogs and had plenty of room still to move around.  Set up and take down were both pretty easy and having the directions sewn into the bag is genius!!
