The luminous stars and dots of this company, I can highly recommend. They light great !! I have held first out of the box about half a minute under the desk lamp and so "activated". It was everywhere, it will not function. So it went anyway and after the darkening of the room you could look fabulous where you can place the star, points, planets, etc. best by the lights. We did this with our son together and was almost over the moon with joy. They adhere well, even if he has stuck it (almost 3 years), so even with not quite as strong solid press-and certainly no longer dust and grease, which of course is beneficial in bonding. We often had to go to his room and make everything dark, so he could watch his starry sky. They shine really long, quite a few hours in the morning and even shimmer quite easily. Maybe that also lies in our night light that my son has adjusted to the blue color. Maybe that gives the stars a little Shading. At first I thought I would need certainly still a black light, so that they radiate throughout, but the way it is is our son completely satisfied and after some initial difficulties he goes now without crying in his bed and does not want to sleep necessarily with mom and dad. That's great !!! I would order it again at any time, at the latest for the second child :) and they came super fast here by letter!
