    Would have liked a choice of dimensions. Adding inches of molding to make up the difference worked okay but, cost $$.

    I am very happy and pleased with my purchase with Sleepy Time. They had exceptional customer care and took a-lot of time explaining to me how the product works and also helped me figure out what I needed for my window treatments. The product is doing what it is promised and I would recommend this product for anyone that needs to have total black out experience at night to sleep. I am very happy with the product and would highly recommend this product and this company.

    The simplest ideas are usually the best. Tracks work great and are easy to install.

    Although I find the light blocking strips to be quite expensive, they have solved my issue of light intrusion as best as possible

    I have blackout blinds installed in my bedroom. While the blinds block out the light; around the edges, not so much. Since I am a light sleeper (pun intended 🙂 I decided to try Sleepy Time Light Blocking Strips to find out if they would solve this problem. The difference was night and day! So, now I’m not awakened when the sun rises. Depending on your sleep preferences that could be good or bad. But for me it is wonderful. Initially I purchased only enough tracks to treat the two windows in the bedroom, because it was a tough sell to convince my wife that the ‘good’ of blocking out the light would outweigh the potential ‘bad’ of adding them in front of our window blinds. But, after I installed them, she thought that the tracks framed the blinds and made them to appear more elegant. Perhaps needless to say, I will be busy installing more Sleepy Time Tracks.

    WOW! I recently moved and did not realize that there was a street light outside my bedroom window that makes you feel like you at Universal Studios City Walk. I purchased blackout shades and they worked fine. However, there was stil bright light coming from the edges. I installed these. (EASY) and now it is so dark in my room I need to turn on a light to see where I am going. I mean it is REALLLY DARK. They work and easy to install.

    I am very happy with my purchase from Sleepy Tracks. The tracks block out all the light my roller blinds used to let in. The customer service was also amazing. Bob was quick to answer any questions I had and helped me select the right tracks for my blinds. This product is amazing and is essential for anyone with roller blinds!

    We installed these in our nursery and in our main bedroom and they made a huge difference in eliminating the light gaps that our cellular shades left. The room is nearly pitch black with the exception of the small light gap at the bottom of the window where it is clear that whoever built our house didn’t know what a right angle was. Definitely reccomend this product!

    No words to explain how happy my son is! Crazy amount of light coming through was waking him every day at 6 am. His room is so amazingly dark now and he’s sleeping so much later! And really amazing how you can still raise and lower the shades so easily!

      Hi Jamie, thank you for taking the time to give us your feedback. So happy to hear their helping your son.

    Sleepy Time Tracks work as advertised and are super easy to install. I used them in a dedicated Home Theater room and they prevent light leakage which spoils the impact of a front projector setup. Great product and super fast shipping!

    I ordered these to go along the sides of a blackout roller shade that we had installed in our toddler’s room as much light was still entering the room during naptime even with the shade installed. While the room is not completely blacked out with use of these strips, it has helped tremendously and we are for the most part satisfied. Our toddler now knows when the shade goes down that it is naptime. 👍🏾

    Perfect! They were easy to cut with heavy duty crafting scissors. I painted them with acrylic paint. Very happy with them! Easy to install and easy to remove with the magnetic strips. I will definitely use this company again for the lower windows next!! Very fast shipping too!

    Our sleepy time tracks order arrived just about 2 days after I ordered them. They were so easy to install and make a world of difference in my babies nursery. She is finally able to take a nap during the day and I couldn’t be happier.

    Additionally Robert and Jan are clearly working really hard to deliver a great product and great service within their small business and I am so appreciative.

    My partner and I splurged on Lutron Serena motorized blackout shades for our bathroom and bedroom (4 windows in total). While the shades are indeed blackout, of course we had light seeping in from the sides of the shades. I was thrilled to find these light blockers online and immediately ordered 4 sets of the removable/magnetic version. These light blockers work as advertised and do an amazing job!!! These are 100% worth every penny.

    I will add nothing in our 1935 Tudor bungalow is completely plumb – this includes the frames around the windows. While we did clean the frames with rubbing alcohol before attaching the magnetic 3M adhesive strips, they did pull away from the frame in a few places, mostly the bottom 1/3. The solution was to remove the light light blockers, drill tiny pilot holes in the magnetic strip adhered to the frame and use a couple small screws on each magnetic strip (middle of the window frame and within 1 inch of the bottom) with flat heads to ensure they stay in place long term. The light blockers reattached perfectly afterwards. This was super easy to do and enables us to remove the light blockers to tilt the windows in for cleaning when we need to.

    Very pleased with our purchase and highly recommend!!

    Great experience overall. Definitely made a big difference in the nursery although our windows are unique sizes and with roller shades there are still a spots where light peeks in through the corners. Took me two tries to get one huge window right, but the company was very responsive by email and worked with me to resolve the issue. Appreciate the great customer service!

    I am not handy whatsoever, but I was able to install these myself in minutes! They do a great job blocking light in my sons room. I emailed the company asking if the product would work for me, and I got a detailed response back with photos within a day. Excellent customer service! Thanks guys!

    Thank you for a great product that works just as advertised! We did install it incorrectly the first time, but that was user error. I suggest to others to read the directions and test the items before actually sticking them on.

    Love these. Got them for all of our bedrooms with roller shades. Really darken the room. Easy installation. Exactly what we were looking for.

    I can see where these would work well on shades that weren’t measured properly and had a lot of space on each side, but ours were measured so well there is not enough space to put one on each side. Our bedroom faces east so we get the early morning sun and the tiny gap we have with the sun shining on our face wakes us up. These are sturdy and well made. I will recommend them to other people, just did not work for us.

    Fantastic! Bought them to block the light coming out of the sides of my French door cellular shades. I can enjoy sitting at my desk without the sun hurting my eyes. Lightning fast shipping, arrived safely packaged and installed them in about 5 minutes. Will be back in the future 🙂
