Window Light Blocker - White 60" Set of 2 (Removable) - Blackout Side Tracks for Window Cellular & Roller Shades - Light Blocking Strips for Bedrooms, Nurseries and Media Rooms

Finally an affordable solution for a problem that would cost a lot of money to fix with new window treatments. Easy to install - all you have to do is measure, cut to size, and adhere to the frame. I now sleep better not having light bleeding through the sides of my blackout window treatments. Added bonus - they are on magnetic strips so you can remove them to clean tilting windows. I found that all other comparable products only had double-sided tape without the magnets. This was a huge value add. I'd recommend this product if you would like to prevent light from bleeding into a room when your window treatments fail to do the job.

We got blackout shades for our bedroom, not realizing the sizable deduction in width taken by the shade manufacturer would result in a 1/4 inch gap on both sides. To make matters worse, that side of the house has more light in the morning than expected. It truly made it difficult to sleep past 5am, my husband 'the mole' was miserable. I started researching which blinds used the least deduction and was going to reorder new blinds with tighter tolerances. This would have cost us $475 for 3 windows, but since all inside mount shades need some clearance to work, we weren't sure this would solve the problem. Fortunately, I saw a comment about Side Tracks for the 'gap issue', which led me to the Sleepy Time Side Tracks on Amazon. The cost for our 3 windows was $130 - not cheap - but if they worked it would be worth it. Well they are AWESOME! They work exactly as described and look good too. We no longer dread daylight. : ) Note: the double hung windows went as expected, for the casement window with a crank at the bottom, we had to set the tracks out a bit more to clear the crank. Having the shade down when marking for the tracks should account for this. Bottom line, we like these so much we ordered side tracks for our guest bedroom. This is a great product that really fills a need!

I am having the same issue as Rox (2018). They install very easy, but when I peeled the tape off and went to line it up on the wall it instantly stuck too far out on the bottom half. I went to remove it quickly thinking I could reposition and the paint was coming off with it. I immediately stopped and just left them where they were. It totally blocks out the light, I just wish I could have gotten them a little closer to the shade, it would have looked nicer. I won't be removing it though unless I want to paint the whole frame. Be aware of that. Maybe I should have peeled down halfway and positioned and then remove the rest. Ahhh hindsight. Anyway, I think they work as intended and really easy to install over all. Time will tell if they continue to adhere. I do think they cost too much though, but I had to get 2 sets 72" long. So far I think they're great and being that they seem to be the only company out there that has anything like this (I like the fact that you can remove the L shape strip to open the windows), they are worth buying.

Have these on 7 windows. Easy to install and work very well.

These sleepy time tracks have been a total game changer! To give some background, I've got a baby, toddler, and older children who only sleep in past 6am if their rooms are DARK. In the past, we bought custom blackout blinds, but there was still light coming in the edges, so we had to use blackout material velcro-ed to their windows. BUT, I hated it because it was a pain to take off to let in light during the daytime when we were awake. So then comes along sleepy time tracks....They block at least 99% of light that came in the side cracks. It was super easy to install and their rooms are perfectly DARK! My kids and partner sleep excellent now and I couldn't be happier!!!!

I'm surprised these aren't more widely available. In fact, I'm surprised the two-sided tape isn't sticking directly to the strip. I needed these since the shades leave a gap at the edges (and next door currently has painters on scaffolding looking in). It's not a huge problem but being able to shut out more light and more snooping is good. One suggestion I would give is to put a small hole toward the top and one toward the bottom of the strip so if we wanted to, we could screw in a small screw to hold this more securely over time. I know, I can and will do it but it would have just been nice to have already drilled small holes. Nov. 2020--have had two of these up now for a while and they do block out light coming in on the side of the blinds. However, the magnet band is fairly weak. When I have to move the venetian blinds to open the windows, they push the Side Tracks off the magnet. I wish they'd put one hole toward the top and one toward the bottom so if the buyer wanted to install it a little more permanently, we could. Also, with time the magnet seems to be getting weaker.

Customer service was fantastic. The product is easy to cut with sharp kitchen scissors and goes on easily. The dimensions were perfect for my window and blinds. And it works, blocking out most of the light from the sides of the blinds. I tried the cheaper knock off versions, but this was engineered better and worth the premium.

We have an east facing window. We get beautiful sunrises. But we also get woken up way too early in the summer because of it. Prior to adding these, we'd installed blackout film and shades on the upper windows. And had blackout blinds and curtains on the ones we can reach. The sun was still waking us up. I installed these Sleepy Time Tracks this last weekend to block out the cracks between the shades and the window frame. The room is so much darker now that it's tough to get up in the mornings. That's not a bad problem. It's great to not have to get up with the sun anymore. They were easy to cut and install, too. I also want to commend the seller with their excellent packaging. Great product all around!

You know when you succumb to marketing spin and are disappointed with a product? Well this isn't it. It works exactly as promoted. We have brand new windows and new window coverings and were disappointed with the light that comes in the side of our new blinds. Depending on the time of year the light falls directly on my face while sleeping, even with the blinds closed. I tried to live with it, but kept looking for a solution and stumbled on this. We didn't want to damage our new window frames. My husband cut the strips down to size, peeled the tape off the magnet and taped it to the window frame and then magnetically attached the flange piece. The end result looks very professional. I hardly ever write reviews, but this product deserves to be recognized.

I highly recommended this item, does a complete black out on the sides of my roller blinds

These are way overpriced for what you get: I could make something like these for under $20 with corner stripping and magnets. The magnets it came with were weak, and it seemed one had the wrong polarization since the strips wouldn't overlap and stick completely. Another problem is that these will only work if they are sitting flush with your blinds. If your blinds are even 0.5 cm from the strip, light will leak through. In other words, if you have blinds that are mounted a certain way or your window frame has molding that isn't completely flat from window to outer frame, these are useless. I would say that these are ok strictly for roller blinds that have top mounts (NOT side mounts) and are at least 1.5 inches from your window. Otherwise, don't bother. That said, they do help a bit, but not enough to make the price worth it.

It blocks out 99% of the light. And it is a cheaper option that buying it from a professional company who would charge at least double the price. I wish I found it sooner!
