My use of this isn't quite typical. My bedroom is in the southwest corner of the house I rent, and as such it can get incredibly hot in the summer. I bought blackout curtains last summer, and, even with permanent metal awnings outside the window, they had rectangular sun-bleached areas by autumn, and my room would still be very warm. On one day I had to evacuate my pet snake to the living room because it was dangerously hot. I needed a solution, and I'm limited in what I can do because I rent.
I ended up attaching this shade with carabiners to the underside of the permanent awning, and attaching the other two corners with tent spikes to the lawn. (See photos.) It's worked terrifically. The curtains in my room used to be hot to the touch in the late afternoon - no longer! Breezes can come through the shade, but solar radiation is mostly blocked. Light still comes though so I can enjoy pleasant natural lighting without being roasted to death. The shade material is sturdy, light, and well-sewn. I'm going to buy a second shade from this company for the side yard to keep the sun from battering my room wall. A great purchase which has hugely improved my living space!
