Amazing!!
These blinds do exactly as they promise. 100% blocks out every ray of light. My 4 month old went from waking at 4.45am to 7.30am!! They are pretty tricky to put on, and looks like you are painting from the outside (maybe I just have more air bubbles than most) but wow. Baby also settles for her naps much quicker as there is not a thing to look at !!!
