Sleepy Time Tracks - Original PVC Light Blocking Strips Made in The USA- Window Light Blocker for Blackout Shades & Blinds- Enjoy Deeper Sleep and Total Darkness (60" White Permanent)

This was the perfect answer to the gap in my blinds! I wanted pitch black in my room and was able to get it with these. They are super easy to install and the quality has been great. I was able to easily cut them with my kitchen scissors and they stuck to the wall with no problem.

Great product and easy to install

We purchased this in 2022 in a dazed state of new parenthood. It worked really well to close out the remaining light and helped our toddler sleep. Two years on, I was nervous about removing it before we check out of our rental apartment. I dug out my order and emailed Sleepy Time Tracks: they were very responsive and reassuring, so I went ahead and peeled it away.Pleased to report it came off easily and cleanly in one piece, with only a slight discoloration of the paint (which I haven't even tried to remove as our landlord is painting anyway). No residue or foam left. And this wasn't new paint either, but probably a decade old (typical white gloss paint of a window fitting). I'm impressed!

they work pretty well, just feel that its overpriced for what is basically 2 strips of plastic thus the 3 stars

This product does the trick but will have slight gaps at corners which would still allow a tiny bit of light in. I was able to utilize a whole single piece across the top of the top end of the window. But the heat from the sun buckled it right after installation. However, I was able to reattach it in the evening. By morning the adhesive adhered in place. Be sure to measure correctly or else even hairline gap will allow light through. Very useful product. Just a bit expensive.

Cost effective solution to blocking most light escaping from the side of blinds

Great product, accomplished what our blackout curtains and honeycomb blinds could not. These were easy enough to cut and measure and work really well in our child's nursery.One thing to note - the adhesive doesn't joke around. Once you set it in place there's no way you are getting it out without ruining it. Be really sure when you are about to set these into place. I made this mistake and set the first beam a little too high. No problem - I covered the gap at the bottom with the extra from having cut it shorter.

This is our second order for this product. works great!
