This has been a great item so easy to cut to size and use repeatedly Suction spot on hasn’t let me down yet Plenty of material to more than cover window and to have a spare for travelling

It blocks out the sun light very well

Dunkelt gut ab

My bedroom is on the east side of the house. In summer, it gets very bright and starts heating up by 6am, so I sleep in my guest room in summer, but it still gets pretty bright. I had 'blackout curtains', but they never worked, then I found they are a holdover from WWII, where they were used not to keep the sun out, but to keep 40 watt lights and candles in so German planes couldn't navigate. No wonder they never work.Finally found this. Light. Thin. DARK.Yeah, it's a pain to install. These self stick things are always iffy, but normally if you restick them well, after a few times it's on forever. Mine partially fell of 8 times the first 2 days. Now it's just up. And I only used 8 stickers: 2 on each upper corner, 2 in the middle, and one each on each side for now.If I sealed the edges, it'd be pitch dark, but I have a portable AC in that room, so the hose has to go out the window, but it's still dark enough that I need the lights on midday.Finally, no more waking at sunrise! But I can't use it on my bedroom because I have a camera and small solar panel in that window, and the temperature inside there would get too high. But that's not their fault, that's physics.

Good blackout sheet, not perfect.Blocked out almost all the light, but some does manage to escape around the edges. Would be better if the Velcro came in strips, rather than circles.

Zuschneiden dauert etwas. Es wäre gut, wenn man die Farbe der pads anpassen könnte, da zb weiß auf braunen Fenstern nicht gut aussieht. Muss man nun händisch dran arbeiten --> Zeit, GeldVerdunkelt super, tut was es soll. Hübsch ist es leider nicht. Weder von außen noch von innen. Man sieht halt jeden Knick.

We needed total UV blockout because of the fact we do not yet have air conditioning while renovating an ancient home's windows, nor are we at a phase to purchase curtains or blinds. With the sun cooking us inside, I found this material and gave it a try. One order was enough to cover three windows and allow us to see the results. We are really satisfied and it's made the indoor environment cool down by 30+ degrees. This is easy to cut and manage; we have had to use thumbtacks for some to keep them up - but it has to do with the old window frames which are impossible to clean. Our windows are over 100 years old and not standard sizes, so we appreciate being able to cut to the sizes we need. Ordering more today!

Ich habe es an die scheibe geklebt und es hielt gut 2 wochen nun hat diese folie allerdings ein thermischen Riss in der scheibe verursacht was mich zu einer reperatur zwingt

It still lets some light in. And u need to cut it yourself. But for the price u do get a big material .

Hat uns trotz fehlendem Sonnenuntergang auf Island nachts gut im Dunkeln schlafen lassen. Funktioniert sehr gut. Haben den Stoff in vier Teile geschnitten.

So eigentlich richtig gut Punkt abzug weil das zuschneiden umständlich ist
