Review on ☀️ Stay Cool and Protected: Winsall Auto Sun Shade with 2Pcs Roller Shades for Car Window - Beat Sun Glare and Heat with Ease by Wayne Drakh

Sticks very well to the window. The suction cups are pretty strong. I was only able to detach it by pulling the small tab on the suction cup. The blinds fold down easily and there is velcro to keep it from moving. For folding, there is a small button on the top of the device that quickly retracts the curtain when you press it. I had no problems with this curtain. One problem I've had with other types of these blinds in the past is the deformation of the suction cup portion. There is a tip in the instructions that tells you to simply soak the suction cup in hot water to change its shape if this happens. If only I had known that many years ago! I am glad that the manufacturer has included this comment.
