Customer Ratings & Reviews

Works well, tried it once. Looks good, easy to install and pair.

It looks seamless, and based off of the test seems to work functionally. However, I was very disappointed to discover that you have to purchase the SimpliSafe base in order to get notifications to your phone; because otherwise, it is simply a normal detector, not worth the price tag.

This is an excellent life safety device. It was easy to pair with my existing system and provides peace of mind to me and my family that we are protected by Simplisafe from dangers both outside and inside our house.

Seems to work just fine. Easy to install and setup. Hope I don't ever get the opportunity to see if it works.

Very good quality and easy to install and pair to system

Only thing I dislike about these i how many batteries they eat up. But other than that they do exactly what i want them to do!

SimpliSafe products are easy to use. High quality and look nice as well. I’ve used them for almost 6 years. Customer service is great as well.

Love to see more smart home sensors for the simplisafe system. Sure, I could rely on our Nest protects (also great) for alarms like these, but we've seen first hand (several times) the need for a failsafe of the system being able to call for help with a monitored Simplisafe system. Notifications while away are just not enough, I'd hate to miss a push notification or be on a long flight and not be able to save our pets from carbon monoxide poisoning or fire. - Worth having. This detector also is nicely minimal and blends into the background. Nice design.

The sensor and system are excellent…decent battery life.

Easy setup and installation. Siren is very loud. I feel safer since installing this device

Simplisafe integrates another great product to my whole house monitoring system with this Smoke & Carbon Monoxide detector. As inexpensive as the same item that can buy however this Simplisafe detector can monitor and give an alert that goes to my phone. Groovy.

So far it has not gone off, so that is a good thing right? I do like that it was not so expensive like the NEST Protects that are like $200 and expire after a few years. So far I love it.

Love simplisafe products. Connected very easy. Like the dual sensor.

Easy to install and add to existing system. Simple instructions make it super quick

Simple to setup, however does not integrate with wired system.

I marked this with 5 stars even though, thank God, I have no idea how this works. What I can tell you is that it was real easy to install and having the piece of mind knowing that it covers both is the best thing

I love having the combination with the CO as well.

It’s been installed for months and haven’t had a single issue. Integrates seamlessly and works great!

Works great and easy to install. It’s nice to finally have a combo Smoke and CO2 detector

Meets needs for desired application, quick and easy install
