Review on 🚨 Digital LCD Display Carbon Monoxide Detector Alarm with Voice Warning - Battery Powered by William Rothstein

Small CO2 Detector. Easy to install, just like any battery powered model. Includes wall molybdenum and batteries. I've noticed that when reading reviews of some detectors, people complain about dead batteries. I noticed that this model had the batteries built in, but one battery per unit was still in the plastic wrap. This plastic is very easy to miss. Also, in some cases, the batteries were installed the wrong way round. After answering these questions, the device will turn on with a voice response and then do a 2 minute countdown to make sure it's working properly and display all the CO2 readings on the small screen. CO2 detectors should be mounted at about waist height and as close as possible to potential sources of CO2. This differs from a smoke alarm that is mounted high, such as on the ceiling. This is a good unit with a good detection system.
