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.

  • 10-Year battery backup means constant monitoring for the life of the alarm even during a power failure

  • Indicator lights display the presence of smoke or carbon monoxide; an 85-decibel siren provides loud warning upon detection

  • Single test/silence button

  • Adapter plugs included for simple installation when replacing other branded alarms

  • Smoke and CO alarms should be placed on every level and in every bedroom of the home

  • Tested to meet UL standards

  • 10-Year limited warranty

Garbage!!!
Size: 6 Panel
The description of this item claims it is a room divider for patio privacy. The problem is that a little gust of wind and down it goes. Ther's not much privacy when it's always on the floor. This poor design needs some braces on the bottom to give it some stability and keep it from blowing over. Mine came damaged and the seller wanted me to pay $80 to have it shipped back to them despite uploading pictures of the broken hinge it came with. Take my advice, keep looking and don't settle for this one!

Stylish, Sturdy Shelves That Instantly Upgrade Any Bathroom
Size: 15.7", Color: Rustic Brown, Size: 15.7", Color: Rustic Brown
Beautiful, sturdy, and easy-to-install shelves that instantly make the bathroom look more organized and stylish. These floating shelves completely transformed the look of my bathroom. The wood color is rich and warm, and once installed, the shelves look much more expensive than they actually are. They add both decoration and practical storage without taking up extra space. Installation was straightforward, and everything aligned well. Once mounted, the shelves feel very sturdy. The toilet paper holder is especially useful, and the storage box has enough space for two rolls plus small decor pieces. The shelves also have great weight capacity. I added decor, candles, and a picture frame, and everything sits securely. They really elevate the room, giving it a cleaner and more put-together appearance. The set arrives packed well, and the finish has no scratches or flaws. For bathrooms, entryways, or small spaces, this set is an excellent choice. It’s functional, stylish, and adds instant charm to the room.

Good Quality for the Price
Size: 15.7", Color: Black
Surprisingly good quality for shelves made of particle board. They look nice and hold quite a bit of weight when installed properly. I ordered another shorter set of floating shelves from another seller on Amazon. Those shelves were of especially horrible quality when compared to these.
