Document: really nice pop up tent for the price. My daughter and I set it up in about 45mins. The LED lights are awesome!! they are nice and bright for a very dark area. I took it down by myself in a few minutes and it stores nicely in the canvas bag that is supplied.
Love it. It works perfectly and love the lights in it. Excited to see it at night. Business will be booming
