Great idea and really bought them for going on holiday but they have proved very useful in the summer weather with all the light coming in so they are a permanent feature on my little one's nursery window right now. I do take them down every day and once you get the hang of this its quite easy. I don't fold them down every day but just sit them against the wall ready to be placed at bedtime. I like that they fold up into their own bag for when we go travelling. I wouldn't say our windows are large but they are too large to use just one blind so I've had to use both out of the pack which makes them sit outside the recess on the wall section. Not too much of an issue just need to place them right to stop seeping light. I think this is something I will get years of use out of and would recommend them to others and I would buy again.
