Used it once for camping. There are no noticeable stains or damage. It can be set up in seconds. Takedown also takes only 2-3 minutes. Since the parts are not separated, you can set it up and take it down instantly, like a folding umbrella. Also, the ceiling is double-layered, so it's fine for sunlight and rain. There are also ventilation mesh sections on the sides of the ceiling, so it won't get stuffy inside. It's easy to use, yet you can spend a comfortable night camping. It's a really good product.
