Blackout Tape 1.2 inch x 66 Feet Dark Masking Stickers to Blocking100% of Light, LED Cover Shading Tape for Windows, Electronics, Blinds, Aquarium, Indicator, LCD, Routers, Lamp Strips, Dimming Sheet

This tape is awesome! Wish I’d discovered it earlier. It easily blacked out the annoying glow from a couple power strips in my bedroom. It doesn’t have a strong adhesive. It’s almost like it’s held on by static. So it should be easy to remove. You cut the size you want, peel off the backing and place it where you want it. I’m going to start packing some in my bag when I travel since there always seems to be little lights in the room that bother me when I’m trying to fall asleep.

Solved my problem ! Sleeping better now.

This is exactly what I needed to keep out the light!Recently diagnosed with eye cancer, I’ve been desperate to keep the sun out of my eyes because it hurts so badly and it’s terrifying.Using this and another product to blackout my windows was exactly what I needed. Functionally it does exactly what I need it to. It’s very sticky and it sticks to itself very easily and can easily get twisted around, so that’s not great but it really doesn’t matter because it does the job.If you need blackout tape, this is exactly what you are looking for, without question.I would definitely buy it again and I would definitely recommend it!

Does great job, ends slightly tend not to stick but happy with overall performance

Blocks all light to the point I'm not even sure if it is day or night

I bought this expecting to be able to cover up LEDs throughout my bedroom and my alarm clock, but the tint strength is too dark.I wish that there were more options than this one roll. If this listing had multiple tints to choose from, it would have been more useful. As it stands, this should be used to block only the brightest LEDs.I wanted to use it on my alarm clock but it made it unreadable. This is a great product idea but definitely needs some variability and perhaps maybe a percentage number for tinting strength. I would say this is probably somewhere in the vicinity of 80 to 90%.

Yes. It works. Thanks

If I could leave negative stars for this product I would. It has less adhesive on it than electrical tape. The only thing I can get it to stick to is itself. And it's very thin and stretchy, it does not hold its straight side edges because of this, even peeling it off itself from the roll it lost it's shape, looked awful. Don't spend your money on this one.
