SEEYE Blackout PVC Light Blockers for Window Blinds and Shades, Light Blocking Strips Block Light Along Two Sides of Windows for Bedroom Nursery, Easy to Install(White, 17" L x 1.4" W x 0.8" H-6pcs)

Daylight in summer is an issue for our toddler and visiting family, so we bought these to cover the gap between the blinds and window frame. They made a pretty significant impact on the light pollution from those tiny cracks. The fact that they are magnetic (come with magnetic strips) worked beautifully because we can easily remove them when we don’t need them.They were a cost effective, safe solution for our situation. 👍👍👍

Great product overall, does what it is intended to do. Only issue is the magnetic part isn’t very strong, so a toddler can easily remove from wall. I already seeing this being a game with my little one 😩

Not only does the adhesive not stick, these don't block any light on either side of the blinds or shades.

The concept of using magnetic strips to hold these in place was a foolish idea. It does not stay attached. Simply using 3M tape to adhere to the window trim would be far more effective. Do yourself a favor and find a brand that sells it with 3M tape instead.

It is a good product, the size as required

Really like this, it’s a little hard to stack them together so they are seamless but great product, exactly what I needed

The tape on the magnets came off in literally one night. One even fell off right after I had pressed it on the wall (quite firmly I should add). Product does block light well but I would buy some different 3M wall strips to hang on the wall

These would be great…if they stayed up. I have put them up at least 6 times. It does block the light off the side gaps of my blinds.

“Sticky” Magnet strips don’t adhere to the wall so had to use no more nails. Magnets are so weak that the light blockers don’t stay up

For this for wedges of plastic price I would have expected at MINIMUM being able to serve their sole purpose of blocking out light. Alas, if only dampens it into a orangey glow. Maybe this would work if black or grey. Terrible. Don’t.
