SEEYE Blackout PVC Light Blockers for Window Blinds and Shades, Light Blocking Strips Block Light Along Two Sides of Windows for Bedroom Nursery, Easy to Install(White, 17" L x 1.4" W x 0.8" H-8pcs)

Me encanto el sistema de instalación. Se pega en ambos lados y luego se une magnéticamente, lo que permite sacarlos y moverlos si hace falta.No evita al 100% el paso de la luz, diría como un 80% o 90%, pero mucho mejor que la abertura inicial.

We got this device to darken one of our rooms. We where unsure if it would actually work and I have to say, we where shocked! It really does work! The only reason that I did not give it 5 stars is because we did not put it up as intended. We put it up backwards and instead of using the magnetic strips we screwed it directly into the wall. This kept it out of the way and we don’t need to take it up and down.

Fácil instalación sin embargo dejan entrar algo de luz ya que son muy delgados.

Once I figured out that the magnetic strips were supposed to be installed on both the wall and the product, it was easy to install but I'm still not sure how long it will stay up. Instructions regarding this would have been nice.

Great product overall, does what it is intended to do. Only issue is the magnetic part isn’t very strong, so a toddler can easily remove from wall. I already seeing this being a game with my little one 😩
