Excellent ! SUNOFF Cordless No Drill Blackout Cellular Shades, Honeycomb window blinds
Color: Blackout-white
Size: 46.5"W x 48"H
SUNOFF Cordless No Drill Blackout Cellular Shades, 46.5" W x 48" H, White. This is a fantastic high quality manufactured window shade. It comes in a very large variety of sizes, a good assortment of colors and you can get in not only black out feature, but also light filtering variety. When it arrived, I was highly impressed when I took out of the box. This shade drill-Free Installation, No Damage to window framing area & provides High Stability: Feature a dual-spring tension mount system for fast 1-minute tool-free installation. No drilling, no tools and zero damage to window frames. Balanced double-side tension prevents sagging and supports up to 30kg, fitting wood, tile and concrete windows. It even comes with the a little wrench to tighten the bolts after mounting in window to secure tightly. I had it installed in minutes. It fit perfectly! We had new kitchen windows installed & the framing no longer allowed the old window shade we had to fit. The way the frame was now was very tight not allowing for drilling or having to cut out the framing making a big, ugly mess:/ I am very glad I gave this shade a try as it fit the bill for us and worked perfectly with out having to cut new molding and fit perfectly in the new tight mounted area with no drilling or making a big, ugly mess! I am so happy! This shade was the perfect solution for us. I am so impressed with this very high quality window shade. We got the room darkening & and it truly IS room darkening! Constructed with dual layers: dense non-woven fabric plus composite aluminum reflective lining. This double-layer design fully blocks sunlight and UV rays for total blackout performance and maximum indoor privacy. This will help with energy efficiency as well as wear & tear to interior of my home from the sunlight at certain times of day protection areas from fading etc. This shade not only is Energy Saving Thermal Insulation from blocking the harsh strong sun at certain times of day but also provided Noise Reduction. The construction of this wonderful blackout shade is designed with hexagonal honeycomb structure traps air to form a thermal barrier. It blocks summer heat and reduces winter heat loss to cut energy bills. Energy saving is important to me & I am sure everyone so this is a great benefit as well as looking great! This shade features and is equipped with an ergonomic bottom rail handle instead of loose pull cords. Built-in free-stop mechanism lets you lift and lower the shade effortlessly and lock it at any position to tailor indoor lighting as you like. Not having pull cords is such a huge bonus. I have fought endlessly with these types of designs in past and very glad to not have that hassle. The shade functions very smoothly and truly truly effortlessly and truly does stay where you want it. Even when you push it all the way up after installing it doesn't creep down and stays put. Make sure to read very carefully how to measure your window measurement recommendations to assure you get the proper size to fit your window perfectly. This is a top-notch high-quality window shade! It is a very good value for such an impressive shade and truly am amazed it stays put & secure. I plan on getting more of these now that I see how well they work & function to replace some of other old ones that are degrading & I have to keep tightening mounts that the screw holes are wearing from years of use :/ The are a very good value for wondow cellular shades like this. A very good investment. I am more than pleased! Added note, these would be also great if you are a renter, you do not have to worry about drilling etc. & you can easily take them with you if you move without leaving any damage behind.

Easy mount blinds
Color: Blackout-white
Size: 34"W x 48"H
These cordless blackout cellular shades are a great option for renters or anyone who wants an easy window upgrade without drilling into the frame. Installation is quick thanks to the tension-mount design, and once in place the shade feels secure without shifting or sagging. The honeycomb construction gives the blind a clean, modern look while helping with insulation and reducing outside noise. The free-stop mechanism is smooth and holds the shade at any height without cords, making it a good choice for a bathroom where privacy and a tidy appearance matter. The blackout fabric provides excellent privacy, especially at night, and blocks light effectively. The fit and finish are impressive for the price. The white housing blends in nicely with white trim, and the cordless handle is easy to grip when raising or lowering the shade. There is a small amount of light leakage around the edges, which is expected with an inside mount, but it doesn't take away from the overall blackout performance. Overall, this is a well-designed blackout shade that combines simple installation, smooth operation, and excellent privacy, making it a solid choice for bathrooms, bedrooms, or any room where light control is important. And for what it does, the price is worthwhile.

Don’t trust the measurements
Color: Blackout-white
Size: 34"W x 64"H
I ordered 8 of these. 34” width for my 34” wide inside window casings and they do not fit. Too tight. The blinds actually measure 35” across. Returning them and finding another company.

Great Fit and Surprisingly Easy to Install
Color: Blackout-white
Size: 32"W x 48"H
I’m really happy with these cellular shades. The measurements for my blind were perfect, so it fit the window exactly as I was hoping. The drill free installation was another big plus. It went up quickly without having to drill holes or damage the window frame. I really like the cordless design too. The bottom handle makes it easy to raise or lower the shade, and it stays wherever I put it. The blackout feature works very well and does a great job keeping the sunlight out while giving plenty of privacy. The honeycomb design also feels like it should help with insulation, which is especially nice during hot or cold weather. It looks clean and modern, fits perfectly, and was much easier to install than I expected. Definitely a good choice if you want a blackout shade without drilling into your window frame.

I’m really impressed with these shades! The drill-free installation was quick and easy, and I love that I didn't have to put any holes in the window frame. The cordless design is convenient and gives the window a much cleaner look. They do an excellent job blocking out light and provide great privacy, while the honeycomb design helps keep the room more comfortable. The free-stop feature also makes it easy to position the shade exactly where I want it. Overall, these are a great combination of style, convenience, and functionality.

Clean Look and Strong Blackout Effect
Color: Blackout-white
Size: 36"W x 64"H
The cordless design gives this shade a much cleaner appearance than traditional blinds with hanging cords. I also like the honeycomb style because it looks neat and modern rather than purely functional. The blackout material is a good choice for bedrooms or anywhere you want to cut down on incoming light. The no-drill design is especially appealing for anyone who doesn't want to make permanent changes around the window. For a blackout shade, it combines a nice appearance with practical features.
