Baby doesn't sleep well when traveling, and one of the main reasons seems to be when rooms are lighter than her blacked out nursery. We ordered these in the middle of a failed nap and as soon as we put them up she started sleeping better. Much easier solution than some of the other travel blinds.Exactly what I was looking for to block out my neighbors bright porch light at night. It makes the room actually completely dark. Very easy to hang and it stays put. I love that it’s easy to put up and take down if I want to move it.This worked perfectly we are in a rental in PHX and do not want the hot sun in our room. BUT we also didnt want to put holes in the wall to repair later. so far in 115 direct sun this has worked great! it has oly fallen when my daughter was pulling on them from behind the blindsIt works very well. It keeps my room dark, it comes off from time to time but is not badMy husband and I are obsessed with these. This is the 3rd one we bought. When we have guests in our guest room it gets pretty bright even with the blinds. This stops the light from getting in. Then we can take them down when our guests leave. Highly recommend!I live in an apartment, and try to make minimal holes/mess etc because I actually take care of my things/places I live. I needed an alternative to hanging traditional curtains on the wall.With the absolutely pointless daylight saving time, I am now woken up by light every day and can’t sleep in due to it being light earlier. I also see the car lights of people in the building across from me. Sleeping eye masks don’t stay on/are uncomfortable. When I saw these, I jumped in excitement. I hung them up immediately and am going to see how they do tonight. I will update my review if they don’t stay up/work as advertised.Suction cups do not stick. Had to buy command hooks today to see if that will hold up the curtain.Some suctions cups did not hold well but love the block out.This gets the job done when it comes to keeping the light out. However, and as pointed out by other reviewers, the suction cups aren't that powerful and they get deformed over time to the point where they are almost flat and they tend to fall very constantly. One way to solve this issue is to get the cups moist, that should do the trick. Also, the velcro that is used to contract its size is starting to wear down the fabric around it. So I'm not too confident on the quality of the product, but it gets the job done for a reasonable price.You never know how much you need something like this till you have it. The little one goes to sleep so much better having a dark room now. I opted for 4 stars only because I find it’s not blocking out all the light. It’s 100% better then it was though. Super easy to install and you can take it with you anywhere. Good for longer/wider windows too. Good quality and good shipping.I was searching for the perfect black out curtain and wasnt convinced any of them would work. This one is amazing! i was skeptical that light would get in on the sides due to the fact that the suction cups were only on the top but it blocks out 99.9% of the light. The suction cups work great so far as well!Also comes with a little bag for travelling. Highly recommend!this is the largest size I could find for sale but it's still too small for my windows. most new condos have 9-10 foot tall windows and this blanket is only 6.5ft tall. however it still covers enough glass to allow me a comfortable sleep. the suction cups are flimsy though and they require some heat and forming to make it work well. overall i dont think it's worth the price but there really is nothing else at this size.This would be a great product but the suction cups aren’t strong enough and the weight of the curtain is too much that the curtain falls off the suction. Especially when it’s really hot out, the heat softens the plastic making it that much easier to fall off. It’s great other than that. It does black out the room
