Review on 🔋 10 Year Lithium Battery-Operated 2 Pack Photoelectric Smoke and Carbon Monoxide Detector with Sealed Smoke Alarm by Jose Isaacs

Can't believe how expensive smoke alarms are these days! While it's definitely cheap insurance, I hate it when these manufacturers and sellers charge people close to $40 for something that obviously costs around $5. Installation was easy and so far they are working well. The instructions were a bit difficult to understand and actually differed a bit from the actual alarm function; Still, I give 4 stars because everything seems to work as expected. Definitely a bit cheap considering the cost, so minus one star for that.
