I received this Carbon Monoxide Gas Detection and I was able to install the AA batteries. Literally plug and play. I'm very pleased with the ease of installation.The whole process takes just a few minutes and only requires a screwdriver ,no need for extra tools or labor. I will definitely buy 3 more to put in our room.
