Nest Protect Smoke & Carbon Monoxide Alarm Wired S3003LWGB is rated 4.5 out of 5 by 35.
Rated 5 out of 5 by from Nest smoke alarm Very good product I have been building my nest products and this smoke alarm is well worth the money. I have two and after you have done the setup added it to your Wi-Fi it talks to the next smoke alarm and helps set it up for you.

Rated 5 out of 5 by from Expensive but worth the money This is the fifth of these products I have purchased. Whilst the price is eye watering the quality of the product is outstanding. I think it was Which? who rated this the most sensitive alarm they reviewed. The excellent sensitivity does not mean that it is forever going off unnecessarily. I would say with confidence that it alarms unnecessarily no more than other alarms I have bought and probably less. The fact that it detects smoke and carbon monoxide means that you are getting two detectors in one. Installation is a doddle. The Nest phone app is great and allows configuration and monitoring via your mobile. You can even test the alarms via the app. The light which you can program to come on when you are in the vicinity of the alarm is a nice touch when wandering around the house at night in the dark. The voice alerts are clear and the alarm tones sufficiently load for the purpose. Yes, this alarm is expensive but if you want the best then look no further.

Rated 4 out of 5 by from Great product but a bit dated I love these smart smoke alarms (good features, easy to install) but was a little bit peeved when I noticed the date on the label. They have a built-in lifespan of ten years and a year had already passed, meaning in effect we only get 90% of the value.

Rated 4 out of 5 by from Easy to set up we already have the nest thermostat, so this seemed a sensible option having read good reviews. Set up is easy, not sure how useful the pathway feature really is. my one big concern is that it has a 10yr life which seems to be dictated by the manufacture date, not installation date, so by the time we got ours it only had 9yrs left. I am not sure how you could ever get the full 10 years. As it was on offer & we had a voucher we decided this was acceptable but I would not have been so happy if paying full price.

Rated 5 out of 5 by from Great product Great service Really happy with the Nest Protect, super easy to setup and the nightlight feature is fantastic. Toolstation were the cheapest and shipped it to me really fast, zero complaints.

Rated 5 out of 5 by from Worth the peace of mind These are brilliant. Easy to setup and install. The night light is a fantastic feature. Well worth investing over a standard smoke alarm.
