The sensor and other electronic lights in our trailer are intolerable for good sleep. Have no idea why the manufacturers think we need six lights to shine all night long. But this tape works like magic! Love it! I see some have had issues with a lack of stickiness, but we have not experienced this. In fact, I have pulled the bit of tape on and off the microwave light multiple times and it still works so well. I just leave it lightly attached to the glass during the day, place it back over the light at night.

Don’t put this on your windows if you ever want to be able to remove it!

the adhesive solvent was leaking out of the sides on arrival, the layers placed improperly, Do not buy this product.

This is great for blocking out light pollution from indicator lights on things like monitors, devices, chargers, power strips, etc. Blocks out the annoying lights that would otherwise be visible in my room when it’s dark. Lots of tape, easy to cut, and haven’t had any problems with it falling off. Does exactly what it needs to.

After getting black out curtains in my room everything that had a light stuck out like a sore thumb when it came time for me to sleep. My room was a glow with the lights from the led for my computer monitor, tv, and air purifier. So I ordered this tape to try and block the light. It does a very good job on the monitor and tv led but the air purifier has a really strong light so I doubled up the tape and it now blocks that too. Be warned like any thin tape with a backing covering the adhesive it can be difficult to remove the backing to expose the adhesive. Overall the tape is great at blocking the light and you get so much.
