Review on 🔋 10-Year Battery Powered Smoke and Carbon Monoxide Detector, Dual-Pack Portable Fire CO Alarm for Home and Kitchen by Jeremy Monroe

They were purchased on June 22nd, installed in 2-3 weeks; However, one of them has now started beeping (indicating a low battery). The batteries in this device are not replaceable. My other issue is that I woke up to the smell of smoke a week before the device beeped. My child burned food in the microwave. The devices NEVER made a sound. Couldn't the smoke reach them? My goodness why not as the food burned so badly as did the microwave which I also threw away. It's past the return period (July 24th I think) but I've contacted support. Hopefully they respond and want a refund (preferably) or a replacement. If so, I'll update my review with more information.
