Yep. I have a pair for the front windows on my Astro. Very convenient to stick on, very easy to store. Nice to use in warm weather camping as we get decent flow-through if both the front windows and pop-top window-flaps are open.
I have a set and have used them a few times. They work as advertised and seem like they will last a while if cared for properly. Magnets are strong and would take some serious wind to knock off
