Review on 🔥 First Alert SCO7CN Combination Smoke and Carbon Monoxide Detector: Voice & Location Enabled, Battery Operated - White by Andrew Jenkins

I have bought three of these detectors. After 1.75 years, one of them dropped out. I contacted First Alert to claim the 7 year warranty as instructed. They told me it was out of stock and sent a "poor quality" replacement. The one I have (model #SCO7) has a power/smoke alarm LED and a CO LED. You can also change the batteries by pulling out the side battery compartment of the SCO7. When replacing, the device must be removed from the wall. Also, they charged me $6.50 to ship a replacement. The warranty says they can replace with a similar product. This means that you will be cheated regarding the product you are purchasing as it is conveniently absent from this model when you request a replacement. The replacement unit (model #PVC700VB) has no LEDs and you will need to remove the unit from the wall to change the batteries. Very bad service and reputation in my opinion.
