Nest Protect Review (Expensive, But Is It Worth It?)

It includes photoelectric and ionization sensors (called the split-spectrum sensor), which detects both fast-burning and smoldering fires. It’s a bit expensive, but with its dual sensor, carbon monoxide detection and smart technology, is it worth the steep price?

Positive Reviews

I have two of the battery smoke alarms in my house and one wired smoke alarm in the hallway. Brilliant piece of hardware. I get a message from the wired smoke alarm when the power is out, all smoke alarms chime together when something is up as well as the phone. Best of all, the smoke alarms check themselves. Best home safety product out there. A+++ – Uncognito, Verizon Wireless 2016

I purchased this because I moved into a home that had a smoke alarm probably from the 50’s. It was gross and I am sure didn’t work. This product looks great and the wireless control from your phone is perfect. It is great to be able to check on the status of your home at any moment. – Kentilsha13, Best Buy 12/18/2017

Negative Reviews

Nest is not customer service friendly. I purchased the Nest Protect and found inside the package it is already 1 year old. I wrote and complained and they stated they would replace it and expedite it. Go with another brand that will actually stand by their product. – inthezone, Best Buy 2/3/2017

After installing them into my 3 group homes found out that you can only monitor 2 homes. You can set up another email account for the third one however the app will only monitor 1 email account. A waste of resources for the third home. The units only communicate with Nest units and doesn’t listen for other smoke detectors in the unit. Steam from the bathroom still sets it off. – PortlandRanch, The Home Depot 12/12/2017

I have a nest protect and love it! However when we got a new router it stopped working. Have tried everything including troubleshooting with Nest. It’s a few years old though so might be the software?
