I just received it and opened it in the living room, easy to set up I must admit, just like more expensive tents I had in the past with the same mechanism. However, the fabric is almost completely transparent and thin. I thought it couldn't be true, so I took it outside in the sun and it was indeed completely permeable to the sun. It was like a greenhouse inside. Completely unsuitable for the beach, not only does it not provide shade but it will dangerously increase the temperature. Straight request for a return.
