Review on 🔳 Camco 42913 Retractable Lights Out Vent Shade (Cream) - Ultimate Window Protection - 14 Inch x 14 Inch by Brandon Teitel

Good product with subtle room darkening. It's not 100% but still better than using tape and cardboard which fall off in the middle of the night waking you up and defeating the purpose of darkening the room. Another cool thing is that since it is attached to the ceiling, you don't have to worry about storing another item or else it will be lost. Ease of installation. It comes with mounting screws, but as my air vents were recently replaced I reused my existing screws and used the ones that came with the kit as extras. The supplied tongue screw was a bit small so I used one of the supplied mounting screws. The tabs slide over the umbrella rail, making it adjustable, but when you press the button to retract the umbrella, hold it with your other hand to keep it where you want it. I'm buying 3 more to install.
