I put these blinds in my house 5 years ago and one broke. I was able to order its replacement that day and it was ready for pickup the next day. And even though some of the blinds looked the same, some parts were updated. but I was still able to use the existing brackets on my wall. And it was the same brand. Everything was perfect.

Clean look and incredibly easy to use!

User April 9, 2026

I am very impressed with these Mainstays cellular shades. The cordless design is a game-changer—it moves smoothly and stays exactly where I set it. They provide a nice, clean look to the room while still letting in a soft glow of natural light. Great quality for the price!

Worth the money!

Rhonda February 16, 2026

These blinds are definitely worth the money. They are very easy to install as they come with a template to mark where to put the screws. They black out all the light except the little bit at the edges, but I have drapes that cover that. I am very pleased with my purchase!

Total darkness!

anonymous May 11, 2026

Our bedroom windows face east and south, lotta morning sun. Other room darkening shades never really did the job. These shades give pretty much a total blackout. My husband just finished hanging the last one. He shut the bedroom door, pulled down all the shades and closed the curtains. It was so pitch dark, he had to feel his way back to the door. The fit was true to the measurement given. Installation was a little tricky because we have replacement windows and the space for the brackets was a bit less than needed. Hub angled the screws and the fit is just fine.

Cheaper quality, softens light.

Zack March 24, 2026

For the money, it's a good blackout shade. Installation is fairly easy. You'll need a drill, as you'd expect, but the instructions are easy enough, and they even include a cardboard template for penciling in where to drill the mounting holes relevant to the corner of your window. It's a fairly cheap, plastic blind with think metal brackets. If your house gets a lot of traffic and balls thrown around and stuff, you might want to get something tougher, like wooden blinds. But if you're careful or just don't mind cheap stuff, it's a decent enough shade for the price. The light-filtering is a fair description; a good bit of light still comes through, but it's significantly softened. It's just barely enough light to read by, to try to give you some reference. Don't expect it to darken the room very much, but on the bright side (see what I did there?), you can still do a fair amount of work with minimal artificial light. Long as you don't mind on the cheaper quality side, they're good blinds.

Cheap in all senses of the word, but okay

Zack April 20, 2026

The bad first: this is a cheap blind. The material is minimal, the plastic is thing, the installation is fairly easy but not terrible secure. If you have active people or animals in the house, this is not the blind for you. It'll get destroyed way too easily. That said, if you're a careful person or not a terribly active household, this could be a good option. The good: the blackout is near total. Our room is nearly pitch-black (just be sure you measure first to get the right size blinds). We've had them up a month, and so far no problems. Long and short: easy enough cheap blinds. Good enough, but don't expect to be wowed. All in all, I'd recommend them so long as you know what you're getting and are okay with cheap and will handle them carefully.

Cheaper quality, but otherwise work good

But if you're careful or just don't mind cheap stuff, it's a decent enough shade for the price. The blackouts really block the light; when the shades are drawn at night, our room is nearly pitch-dark in spite of having a streetlight outside our window. Long as you don't mind on the cheaper quality side, they're good blinds.

Wasn't What I Expected

MomOfThreeKidsUnderNine June 24, 2026

I probably should have read the item description more carefully on this item before ordering. It was easy to install, easy to use and looks nice. However, the material it's made out of is questionable. It feels flimsy and I feel at any time, the pets could easily destroy it. However, with that being said, it's been up for over a week. The pets have left it alone and it still looks good! I guess the verdict is still out on this one. It does make the room significantly darker!

Not convenient the store doesn't stock the size I needed, so I had to purchase Walmart for free delivery. The blind super difficult to snap into place... One side pulled out while pressing with so much force to snap into place.. Installation disaster...
