X-Sense Wi-Fi Combination Smoke Alarm and Carbon Monoxide Alarm with Replaceable Battery, Smart Fire Alarm Compatible with X-Sense Home Security App, SC07-WX, 1-Pack

This is an excellent dual smoke and Co2 alarm. Very easy to fit and instructions for use clear and straight forward. It's even idiot proof when you fit it into the mount as if you have not moved switch to on, it moves it as you rotate to lock in place. Testing very good and runs through an audible and visual test for both alarms and then let's you know if both passed. Battery says 10 years but I'd be happy at the price I paid if it lasted half that time. I also tested it after fitting for real smoke and it alarmed as expected and silenced by pushing button once (only added that as most know how annoying they can be when you try silencing them and end up pushing the button about 10 times before getting ready to hit it with a hammer !!) Overall excellent product and would definitely recommend

Seems pretty good, solid and modern looking. I've tested it and all is working just fine. Good instructions and easy to install. Delighted with my peace of mind purchase

This X-Sense Combination Smoke and Carbon Monoxide Alarm with LCD Display, has a 10 year battery life and is definitely worth paying extra for. It is pleasing on the eye, simple to install, use and carry out a test. A green led flashes every 60 seconds to show all is well which is reassuring. WARNING......... The Alarm sound is VERY Loud!

Good profuct

I had another combo alarm that took AA batteries, and one day recently it started bleeping, suggesting a leak of carbon monoxide, so I was forced to call gas emergency. It turned out to be a false alarm that resulted in a lost afternoon, but it gets worse. When they come out, the boiler and gas are switched off and cannot be turned on until a plumber has checked them out, so we had no hot water for a couple of days, and then I had to pay £140 for the privilege of an unnecessary service. The moral of the story is to get one like this with a 10-year battery life, that is better made, reliable, and easy to use, with a precise readout on the remaining battery life. It was easy to set up, and if I hadn't tried to save a few quid with the first one, I would have avoided all this hassle. This one is top notch in every regard, so lesson learned. It was aso very easy to assemble and set up.

Very good easy to install & connect to your router

Just recently purchased this combined smoke and CO2 alarm so can't comment about its longevity but it seems well made. Compact in size and much neater than having 2 separate alarms. I like that it comes with its own mounting base so to remove it just comes down with a twist. Looks smart and can be silenced with just a press. On testing the alarm it is very loud and shrill. Two different types of beeps to distinguish between which alarm is sounding. It has a 10 year battery which is the lifespan of such devices so no need to worry until then. The price was good, cheaper than buying 2 separate devices. So I'm happy with my purchase.

Excellent value and quality
