This thing is huge! I love it! Set it up in my living room when it arrived and my niece and nephew loves it! It easily fits my whole family in there (8 people). Took it to the beach and it was great as well. The only thing is the set up and tear down is not as easy as it seems. I have to pull REALLY hard for it to snap in place when setting up and I have to push REALLY hard for it to tear down. But I think it just might be the fact that I'm 5 feet and it's a bit over where my arms are at. I'm sure it would not be as hard for other people.
I highly recommend this product. My friend is extremely sensitive to the sun and we took it to North Carolina's beaches. It worked very well and protected her! Easy assembly.
This was not easy to set up due to the fact that is was shipped with two of the poles crossed over one another. I highly recommend you open and set it up before going to the beach. Once my husband and I put the poles in the correct place (after much cussing on my part) it work great.
Our kids mostly wanted to stay in the water anyway, but this was snug for two average sized adults. We got our dog in there and it was super tight. Don't expect it to hold 4 people. Otherwise, decent sun protection. Made our beach time much more pleasant.
