MySpyBlocker Light Blocking LED Covers for Routers, Electronics, Appliances and More. Contains 248 Stickers. Blocks 100% of Light

IDK about you but my bedroom has to be pitch black in order for me to get a good nights sleep. If there are any glaring lights (ie. my cable box), they are always positioned so it's at eye level when I'm in bed and there it is, glaring, staring me right in the eyes - did I see something move, did the light flicker?? My husband found these and purchased them and in all honesty - I say save your money - they do come in different shapes & sizes but I have found black electrical tape works just as well if not better. I personally wouldn't have purchased these, but my husband purchased these. I would recommend only if you are a PERFECTIONIST, the circle cutouts, the square, rectangle, etc. They work but I personally would not have purchased.

My boyfriend is a huge advocate for sleeping in totally dark rooms. A lot of my electronics have little square or circular lights that put out a ton of light at night, and he was covering everything with sticky notes. I decided to try these instead. They are pretty nice, but I need to double or triple up on the stickers for most of the lights in my room to make it completely blocked.

I have a Magnavox television in my bedroom and for some reason the designers have a red light that shows when the television is off. I used one of the round stickers over it and it is perfect. I also used it on my camera lens for privacy on my phone. They easily remove and slide right back in place again. You get so many of them that if they lose their stickiness it's no big deal. I have one on the people on my door so that somebody outside cannot just look in my apartment. Again, when I want to use the people all I have to do is remove it.

These work pretty well in blocked light. My only complaint is they aren't "sticky" like an actual sticker, they only cling to surfaces, which doesn't bode well when on a vertical service (like over the light from our tv). It covers green and red lights very well, but the blue light from our tv shines through if we only use one sticker. We've tried to use two but because they don't "stick" and only cling, that's not really an option.

They block light and webcam sure, but I've had to go through several stickers already because it doesn't want to stay over my webcam and every time it falls off I think there's a giant spider or something coming to eat me in the dark as it passes over my monitor.

I bought a new printer and the power light flashes when it is power saving mode. It is in my line of sight as I try to work so needless to say the flashing light was very annoying. I used one of the square stickers to cover the light and it works very well. I am about to upgrade my table and will use the stickers to cover the cameras on it too as well as the camera lens on my cell phone that faces the user since I do not take selfies.

1. Really bright LEDs show thru...but they are dimmed a lot2. Vinyl cling (rather than adhesive) makes them easily removable but also means they won’t wrap an edge. Only work well on flat surfaces.3. Discovered MANY of the LEDs non stuff are recessed behind transparent plastic. This means the light shows around the edge. Not a problem with the product,, just something to be aware of.

Be aware that these are all pretty small and intended to cover small lights or small webcam cameras. They aren't that sticky. That can be a pro or a con depending on how you look at it. For temporary use, it's definitely a pro. But if you're looking to permanently cover up a light on a device, it wanting to peel off might be a downside.

After a few days the light started coming through if you use just one sticker so over lap with one or two more works fine

Perfect for intended use of blocking out light. Light can disrupt sleep apparently so blocking out LED from sky box routers etc helps aid sleep!
