Review on 🔋 Convenient Walkbee Wireless Battery Pack: Smart Combination Smoke & Carbon Monoxide Detectors and Alarms, Perfect for Bedrooms, Kitchens, Living Rooms, and Homes by Ralph Banks

You will need this if you are using oil for heating or cooking. This includes propane, natural gas, kerosene, oil, etc. or do you have a garage attached to your home. It is imperative that you have a carbon monoxide alarm - and hopefully several. We have a locked cabin that requires you to have carbon monoxide detectors in every room because we use propane for cooking and cooling. In a 600-square-foot cabin with only three rooms, we should have four. The fire department actually came to our dock to check on them. This detector is a smart start to staying alive from fire or carbon monoxide. It's surprisingly cheap and almost wakes the dead from the noise it makes when tested. I was confused and surprised when I received it and read that I needed three AA batteries. I was surprised for two reasons. I also assumed that ten years of life meant it came with a ten year battery. And all other detectors, no matter what they detect, require rectangular batteries. It is very important to have a detector. This is easy to install and inexpensive. If you don't have this, please buy something that detects carbon monoxide. I can't stress enough how important this is.
