Calish Car Sun Shades (3 Pack) Universal Baby Car Window Shades are Best for Blocking Over 98% of Harmful UV Rays While Protecting Your Child from Sunlight and Heat

I have these on the window by my desk and they do an excellent job of absorbing heat - you can feel them heating up. I had no trouble making them stick to the glass and I peel them off and store them on a lower frosted section. They stick really well in both positions. They don't cut out much light, which I did also want, although the heat is definitely lowered. I advise you to retake them out of the storage pouch slowly. I didn't and so I have no idea how to fold them to get them back in, hence why I store them on the frosted window section. Overall, recommended as they do take the heat out of direct sun very well.

Bought these during the heatwave to go on our windows at home (we were desperate at that point!). Although we had them in our home, there were noticeable things that would affect it in the car. It’s not the best shade in the world and only vaguely blocks the sun - it certainly doesn’t stop heat. It also looks awful from the outside of the window - like cling film. They were also a bit wonky from being folded up and never straightened out. Wouldn’t overly recommend them.

Good value, these shades stick well to the window. Good size, although they do not cover the whole side window, so it’s good to have three included in the pack. Have to trust that the shades block out UV as promised as the material seems quite thin.Don’t make the mistake we did and wind down the window with the shade attached - it nearly got jammed!

These stick to your windows no problem, only thing I would say would be to open them asap as I left them in their packet for a month and they were hard to get into their proper shape! Could be bigger as well...

These sun shades do not block the sun at all. There is no noticeable difference to the sun shining in your eyes once these have been installed.

I use these in my office when the sun beats down on me through the window. They work great - would recommend!

Great at reducing sun exposure, however they didn’t fit my Corsa windows. (My fault I should have checked before buying)

These stick to the windows really nicely but could do with being a tad bigger. The pouch it comes with is handy too! Even when I accidently roll down the window with it on, it stays put.
