This thing is great! I love the fact that it opens up without any help....so much nicer than our tent that takes time to set up. It has enough room for my two grandchildren to take naps at the same time. Floor is great but after the kids went in and out several times it was sandy. I did have to weigh it down with our belongings as the stakes did not hold in the sand and wind. I would have given it 5 stars except you need a degree in engineering to put it back in the bag. I followed the suggestion of others and watched the video on-line. Once you figure it out it is easy enough to get back into the carrier. This is light weight and easy to carry. I am very pleased with my purchase.
