Review on 🌞 Car Roller Sunshade Deluxe Set: 2 Kids Black Retractable Window Sunshade Blocks Sun & Keeps Car Cool, Neat Look When Not In Use by Michael Hall

Pretty easy to install and do the job IF they stay attached to the window. Unfortunately, in the real world, the suction cups only last 10-15 minutes and then loosen up. I've tried every trick I know of to fix the problem (make sure the window is clean, wet the cups, etc.) but nothing seems to work. A partial solution is to install the device upside down and pull the shade up. This way most of the weight is on the door but then only a suction cup is holding the curtain and it will come loose over time but not as quickly. Conclusion - I do not recommend it as it is a PITA in real use.
