The First Alert SC9120LBL hardwired smoke and carbon monoxide combination alarm with 10-year battery back-up features an ionization smoke sensing chamber and an electrochemical carbon monoxide sensor. The 10 year battery backup allows for continued monitoring, for the life of the alarm, even during power outages. Intelligent sensing technology is designed to reduce nuisance alarms and one button silences them if they do occur. The latching alarm indicator automatically identifies which unit initiated the alarm, even after the conditions that set off the alarm have subsided. An end-of-life signal enhances your safety by letting you know when it's time to replace the unit. Two locking features prevent battery tampering, and installation and connection to AC power is easy with the "quick-connect" wiring harness. Connect it to compatible BRK or First Alert alarms within a single-family residence and when one alarm sounds they all will.

Clean and functional
Color: Grey
This room divider is very functional and sturdy for a single-panel divider and stands securely without wobbling. The extra-thick material provides great privacy and helps visually separate the space. The neutral grey color looks clean and modern, blending nicely with my décor. It was easy to set up right out of the box and didn’t require any complicated assembly. The height and width are perfect for creating a defined my home office space.

⭐️⭐️⭐️⭐️⭐️
Color: Grey
Very satisfied with this room divider. The construction is sturdy and stable, easy to assemble, and stands firmly without extra support. It separates the space well and provides good privacy. The grey color looks stylish and neat, blending perfectly with the interior. The quality fully met my expectations.

Not so good as expected.
Color: Grey
Pretty poor quality partition. It should hold up to normal indoor ware as long as to don’t touch it. If it is used in a garage (as I did) it will collapse.when subjected to any kind of a breeze at all. I had to reinforce the partition with cross-wires for added support and it was still not enough.

Functional but not attractive
Color: Black, Color: Black
I purchased this to hide my cats liter boxes as he refuses to use them unless they are on the finished side of our basement which is also my kids play room. This functions as I’d expect. It isn’t great to look at but better than cat boxes. Overall it might make a good backdrop if needed. My only complaint is the hex/allen wrench doesn’t fit in the screws provided. If you don’t have an alternative tool that’s a smaller hex it will be annoying to put together.

Does the job!
Color: Grey, Color: Grey
This is a great screen to separate a space The base could be a bit sturdier, but for the price, it does the job! I recommend having a mallet for ease of assembly.
