Review on 🚫 Kidde KN COPE D Photoelectric Combo Smoke and Carbon Monoxide Alarm with Battery Operation and Voice Prompts by Manuel Gfx

If the battery is empty every few months, it immediately starts chirping and talking to you. If it happens at 2am, you won't be able to sleep. You have to get up and change the battery. If they only sense battery power when there's a little more energy left, they might start by tweeting every few hours to help you sleep through the night. This device ruins your sleep. Don't buy this. With the technology available today, there is no need for that. This is a mini nightmare. I warned you! I bought mine at a local big store.
