Customer Ratings & Reviews

We’re very happy with our SimpliSafe System at home which includes security, video and smoke/carbon monoxide detection. It was time to replace an older unit so I quickly and easily navigated Best Buy for purchase. It arrived next day and was easy-peasy to add to my existing system and install.

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 top-rated Detector replaces a Separate smoke and CM Detector. I bought three to replace all the separate smoke and CM Detectors in my house.

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.

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.

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.

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

I like that it has both smoke and carbon monoxide detection in one. Easy to install and program to my existing SimpliSafe system.

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

awesome easy to install product, highly reccommended

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.

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!

Very good quality and easy to install and pair to system

The sensor and system are excellent…decent battery life.

Easy to install and works with my system. I am happy with all of the SimpliSafe products.

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

[Employee of bestbuy] Easy to install and add to existing system. Simple instructions make it super quick

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

Great looking and plenty loud in an emergency. I plan to use these across my entire home
