So far, so good. It has integrated with my google home setup and can communicate with my remaining nest devices. The two main downsides to this (which we can't do anything about if you want a replacement for a Nest smoke detector) is the appearance (this looks bland and boring) and that you need to use the First Alert app to setup the device and not google home.

I was very disappointed when I found out Nest was no longer going to make the smoke detectors. I’ve used for the past 10 years. I was concerned about integrating a new one than working together and would it be as good so far I have to say this is a solid replacement. I’ve had no issues. It’s worked well and I couldn’t be more happy.

replacing one of my nest protects smoke alarms since it expired... this is very easy to setup if you are in this situation since the only thing you have to do is remove the older one from the wire and hook up this new one. You have to have the first alert app (another app!!). But is a painless transition for sure. I tested this new one with the existing ones and communication was perfect.

The detector is easy to install and setup. The voice used on this device is not as clear as the Nest device it replaced.

Nice that it uses same mount and wiring as previous Nest Protect, just wish it had the path light feature. Seems expensive for what it is but can’t put a price on safety I guess.

This would have been better if First Alert had cloned the Nest technology and features. I miss the nightlight. I think that this will be an adequate replacement for my Google Nest detectors.

Yes it's not nest, and yes it doesn't have a night light. That being said, easy set up. Aside from having to download the First App, it was the exact steps as having to install a new smoke detector. And less work than replacing with a different model.

This is a good product as a replacement for the Nest Protect. However, it should have the path lights like the Nest Protect.

Easy to install as it has adapter wires for previous nest and the existing holder works with the new detector. I wish though it would light up at night like the old detector

Easy to install & the app seems fine. But I'm pretty salty about this being the official replacement for the Nest smoke / CO2 alarm, yet the motion activated pathway light function has been taken away. Because of this, I'm not sure I will use this for all 7 of my alarms.. But I 100% would have if it had the same light function as the Nest.

I really did appreciate the motion sensor aspects from the old nest protect unlike some others have mentioned. Also wasn't thrilled that it is 7 year life span versus 10 years like the Nest protect. Haven't seen the sensitivity as others have mentioned yet and hoping it doesn't pop up.

Hi averageAbe, thank you for taking the time to share your feedback regarding the SC5. The SC5 is designed to be a functional replacement for the Nest Protect, offering many of the same core safety features, including interconnectivity, voice alerts with location, and color-coded LED status indicators. However, it does not currently include a path lighting feature like Nest Protect’s Pathlight. That said, we are actively evaluating the addition of a motion-sensing night light in a future version of the product. - Maria

Decent product to replace Nest that Google sadly discontinued. Easy to install as replacement with included conversion kit. Only negative - is no night light built in. Sadly nobody seems to do this though, now that Nest is essentially gone.
