Perfect for my nightshift schedule

These blinds are super quick and easy to install. They raise and lower with ease. Working nights and sleeping during the day, I need a dark room. I use room darkening blinds as well as room darkening curtains. These get the job done. I have them in every room of the house now.

Works well enough

I prefer the blinds that you install with side brackets, but these were okay. Not sure I'd want to buy them again, because the installation was annoying. Not necessarily difficult or impossible, just annoying with how you have to mount them. I like the cordless design to pull them up %26 down.

It works

The installation was ease after I figuring out the position of the hardware. The blades of the blinds are thinner that my own ones. But I understand it makes them less likely to break. Overall, I love the clean look than bulky and dust collecting blinds.
