  • A little expense for what they are, but they do work and are made well
Color: U Channel Custom Size: 44''-115''
I have a Yoolax roller shade in my bedroom that is surface mounted on a window. Quite a bit of light gets past the edges when closed, so I bought these to help cut down on the light leakage. These are very sturdy and have a soft fabric "brush" on the inside edges to protect the edge of the window shade. I had to shorten these channels to fit my windows, I just used my table saw with a fine tooth blade to cut through the aluminum channel. The plastic cover on both ends is removable, just make sure to clean out the channel as there are some grooves that the end piece needs to fit in to lock it in. I used a thin run of double sided tape to adhere these to the outside trim of the window. The weighted bottom of the Yoolax shade fits nicely in the channel and the shade still opens and closes without binding. Looks nice and the color is very close to the metal valance of my roller shade. ... show more

  • Good customer service
Color: U Channel Custom Size: 44''-115''
The U channels were heavy duty & easy to install. My first order did not arrive because it was lost in the great void of the DHL/USPS hand-off (they'll probably be found in the processing facility in Atlanta 15 years from now.) The vendor responded quickly to my messages & had replacements sent out to me immediately. ... show more

  • Two sided tape was missing but a perfect fix
This product works well. We had a professional company install black out shades because of the morning sunshine. But we still had HUGE amounts of sunshine coming thru. This product does well. We are going to need to run to the hardware store because the tape was missing on some of the product.

  • Works really well!
Color: L Channel White-4pcs Size: 79"
Really blocks out light coming from side of our blinds! Easy to install, but need a saw if you need to trim excess height off. First box arrived damaged, but the window I needed it for was short enough that we could use the straight part below the damage. The other four pieces were delivered without damage. Beware that the sticky side sticks HARD so don’t place it until you’re ready. Functions 10/10, delivery was hit or miss. Should probably be packaged with more protection. ... show more

  • Looks great and easy to install
I have roller blinds in my bedroom which means that there was a 0.5”-0.75” gap on each side so I bough 5 pairs of these and now my room is much darker. They look clean and made of thick material. The 3M tape is pre-installed so you just have to measure twice, cut to size and stick it to your window pane. Some reviews mentioned that it is hard to cut. I have a miter saw so I cut through these easily but since they are made with thick plastic, I wouldn’t advise trying to cut them with shears. At a minimum you’d need a hand saw. I had an issue where one of my orders wasn’t as wide as the other and seller sent me a replacement set right away. Don’t worry about these being too wide because they still look great. See my pics. Not 100% blackout because it depends on how your roller blinds were install but for my family, it’s given us 2-3 hours more sleep with the early daylight we get in Southern California. ... show more

  • Good fit. Blocks majority of light. Nice finish.
Color: U Channel White-2pcs Size: 57.5"
Opening of channels should fit most roller shade hem bars. Brushed seals help seal light and prevent scratches or rubbing of parts. Easy to cut with a saw to length. Installation is easy enough if you are comfortable with power tools. The finish is good quality and seems durable. Packing was good. Would recommend. ... show more

  • Great product
Color: L Channel Grey-2pcs Size: 57.5"
I found these because I had been searching for something that could block out the afternoon sun from next to the miniblinds in my home office. I was getting tired of moving my chair to avoid having the sun in my eyes. These were easy to install and they are just what I was looking for. The color is very close to the color of our mini blinds too. ... show more
