CS11 Dual Sensor Smoke and Carbon Monoxide Alarm/Detector for Home

Very happy with this device - well two of them. I had Nest smoke detectors for 10 years but apparently they are so intelligent they stopped working as 10 years is the limit for a detector device? Also Nest has gone down the pan since Gxxgle bought them. So one upstairs and one down, virtually the same size so didn't need to drill more holes in the ceiling. And a fraction of the price. I guess I'll really only know the value of these if the worst ever happens but for now I have peace of mind.

Easy to setup. I also tested it in my bullet grill with a lot of smoke, it beeps lodly. This is the cheapest option if you have fireplace to detect carbon and fire at the same time. Too bad it does not connect to Meross app. It has sealed battery which should match the life of the sensor, 10 years. Quality of Meross devices is one of the top. It it very compact, perfect for low ceilings.

Good luck slotting the alarm into the holder if you're mounting this on the ceiling! Its slimline design (very neat!) means it can be tricky placing the alarm into its holder. Too early to really give proper feedback, although I was hoping for this to be "smart" (as most things from meross tend to be). I haven't noticed the light that flashes regularly to indicate that the detector is working, which is good or bad depending on your take.

Great choice to replace obsolete NEST Protect after sensor life ended.

Easy to install. Comes with all fixtures

Meross is the best

Meross describes this detector as ‘easy to install’… absolutely not the case, unless perhaps you have both an electric drill, electric screwdriver, and extensive DIY experience. I have just spent two hours balanced on a ladder, hands above my head and craning my neck as plaster rains down on my hair. So far it’s still not up.

This product certainly does the job it’s ment for
