Features
- Precise Fit GuaranteeBlinds width will 2/5" narrower for a snug internal installation. Actual Blinds Size is 19.625"W x 64"H. Choose the size SAME or CLOSEST to your window width for INSIDE mount. For Example, if your windows are 30" wide, order 30" or slightly less for internal installation. For OUTSIDE mount, we recommend order (2-4)inch wider than your window width for better coverage. For Example, if your windows width is 30", order size 34" would be okay for outside mount.
- Patented TDBU Control SystemOur innovative mechanical stopper technology prevents the bottom rail from lifting the middle rail, ensuring stable operation. This unique top-down/bottom-up system allows you to precisely adjust the position of the middle rail to control both light and air circulation according to your needs - whether you want full privacy, partial light, or complete ventilation.
- 100% Blackout PerformanceFeaturing a special silver-plated layer inside each honeycomb cell, these shades completely block sunlight and harmful UV rays. This creates a true darkroom environment that's perfect for daytime sleeping, shift workers, or home theaters. The blackout effect helps regulate room temperature and protects your furniture from sun damage.
- Ultra-Safe Cordless DesignEngineered with child and pet safety in mind, our cord-free operating system eliminates dangerous dangling cords while maintaining easy one-hand operation. The smooth lift mechanism allows you to gently raise or lower the blinds to filter sunlight without any cords getting in the way. Enjoy both safety and convenience in one stylish package.
- Superior Insulation & Noise Reduction1" honeycomb is denser than 1.5" competitors traps more air for better temperature control (blocks heat/cold) and 30% more noise absorption. Sleep better, save energy!

I have a little experience with this brand, though this is my first top down bottom up shade. It works. The motion is smooth. It definitely blocks the light well. Installation was very simple. I do wish the bottom had a handle on it, like their shades normally do. Also, when you pull the top down and try to reseat it at the top, it's pretty finicky. It takes me several tries to get it seated right. As far as the brand goes, I definitely prefer the cellular shades I got from a local big name home store with a signature blue color scheme. I find this brand a little harder to push back up efficiently after they are pulled down. Also, I've had some big issues with the sizing in this brand. I'll get one that's not even close to the width it's supposed to be and another that's right on. I've had to return some because of that.

The LazBlinds Top Down shade is a nicely designed blind the mechanism that controls the up and down is smooth as butter and functions exceptionally well. The clip for mounting installed easily after holding the bracket up and finding where the screw needed to go i dimpled the spot then put the bracket down to pre-mount the screw , then installed the bracket. This might seem over involved but is easier than holding a screw gun bracket and an unmounted screw spinning on the top of whatever surface you are mounting to. The shade is in a bathroom and for privacy and it does this well and blocks light. The material is good looking and should hold up. Just decide how you are mounting them and get accurate measurements...the rest it is an easy DIY.

This cellular shade was incredibly easy to install. It glides smoothly allowing for any amount of light or darkness you want to enter the room, and the best part is no cords or plastic sticks to mess with. The quality is great and it gives a clean, polished look. I hung mine in a laundry room, but it's stylish enough for a bedroom, kitchen, or even a living room or family room. Highly recommend.

Love the shade. I like the fact that I still look out the window from the top with privacy at the bottom!! Only thing is get pulled tabs for bottom of the shade to pull down easier
