Review on 🔋 Portable Battery Operated 3-Pack Combination Smoke and Carbon Monoxide Detector Alarm - Ideal for Home, Bedroom, and Travel by Charley Prz

Red Instructions. The base is screwed to the wall. Read the instructions. Added batteries as instructed. The "test" button was not pressed, the batteries are inserted. The noise started immediately and didn't stop. I repeated the instructions, the battery installation steps, but did it on the street - it squeaked and didn't stop. Pressed "test" waited a minute during which he continued to buzz. I don't throw it in the landfill, but I want to throw it away as much as possible.
