easy to use, works well for dimming down all the obnoxiously bright LEDs and displays that are everywhere. Works well in dashboard applications as well. One of those products you vaguely knew you needed, but didn't know someone actually made. Read more

These are simple and effective at dimming running lights on routers, clocks, etc. They don't make things too dark, especially if the base light color is blue, but they definitely cut the extreme brightness in the middle of the night. Easy to apply and outside of moisture they don't come away from a variety of surfaces with ease. Read more

Precut ones are small which is ok for electronic devices but can fall off if handled frequently Read more

I purchased these to hopefully dim the indicator lights on my wifi router/internet gateway and alarm system wireless connection box. Because the main cable line comes into the master bedroom, before being split ti the rest of the home, these devices had to be installed in the master bedroom. The lights on the gateway are blue and green, and light up the entire room. It’s very distracting. I used 5 of the 1/4 circles to cover each light on the gateway, and a strip I cut to about 1/2” wide to cover all of the lights on the alarm system box. One sticker was sufficient to cut the light output by about 60%. I can still faintly see the lights in the daylight (which is what I wanted, because I like being able to see if everything is online, as it should be), and in a completely dark room, I don’t notice them, unless I look for them. They would cast a bright glow across the room, ceiling, etc. before. They are extremely easy to peel and apply (I used tweezers to be able to place them precisely where I wanted them), and the adhesive is more than sufficient. The material also t reminds me of automotive window tint. It’s very transparent, with just the right amount of tint to it. Read more

These work great! You can customize the size if needed. We have a thermostat in our bedroom and these dimmed the light enough that it wasn’t noticeable.. I would buy these again. Read more

I will say it blocks out those annoying little lights. However I bought it for the one on my tv and now I can’t use the remote. So it blocks out everything. So be aware. Read more

This is PERFECT. Our baby monitor screen was so bright even on the lowest setting. It was horrible at night. I cut its shape from the sheet and viola! Then with the page of cutouts I blocked any annoying light in our room and our daughters room. I almost bought a whole new baby monitor until I stumbled across these. Highly recommend. Read more

These things work really well to block annoying lights on electronics. 100% block, not see-through. I carry a pack with me on vacation so I can block annoying lights in hotel rooms! Read more
