Black-out sticker

We bought this to make our bedroom completely blacked out by covering the little lights on the tv and air conditioner. Worked PERFECT! So far it’s a been over a month and they’re holding up well! Haven’t noticed any issues with them sticking.

This might be an unconventional review but I bought these stickers to cover the check engine light on my car. Unfortunately/fortunate for me, my car needs a new engine (not gonna happen especially since the car is worth a fraction of the cost to replace the engine) so my plan is to ride it until the engine falls out (literally and figuratively) then scrap it at the junkyard and get a newer car I’ve been saving up for. Until then, I don’t want to see the check engine light and these stickers covered it up perfectly. Easy application, no complaints.

Absolutely amazing at blocking out the light from anything. Nothing gets through them. They are pretty small but they have some larger ones that I haven't run out of. They aren't very sticky, and they are difficult to get off the package even with the supplied tool. I found bending the sheet works better than the tool for pulling them off. They do their job very well though, would recommend to anyone trying to get rid of annoying lights.

They work even better than I expected. I got the ones that do the most light-blocking, and I don't recommend you use them on anything where you need that LED to make sure the device is still working. As much as my router blinking in my room annoys me, I won't use these on that particular item because then I can't check the indicator lights in the day time, lol. But for all the power strips, the monitor power buttons, and the LED desk lamps that have power buttons that come on when the lamp is off...yes. They are perfect.

So that new fan hums you to glorious sleep and drowns out the barking dogs. But those led lit buttons put out just enough light to distract. These stickers provide total darkness when put over any light source.

I used this on my laptop and it’s awesome. They come in different shapes too which makes it fun. It also peels off safely when you need to correct it. I have plenty left over too! Cost effective and easy to use!

Ddon'twork with all lights, placed it on my TCL tv but while it blocked the light it did not allow the remote to work.

I'm the kind of person that needs near total darkness to sleep. Just about any light that isn't red is like a little laser piercing through my eyelids and making sleep impossible. These magical little stickers BLOCK IT ALL. They are so thin yet nothing gets through. Definitely a good investment. They are also super simple to use. Just peel and stick.
