Pricey compared to regular smoke detectors

Compared to the average smoke detector, the Nest Protect seems like an extravagance. It's more than double the price of a garden-variety device and although it's pretty, it's also something you'll rarely look at. But, when you're thinking about safety,...

Multiple sensors including smoke and carbon monoxide ; Works with IFTTT ; Self-test capable ; Intelligent warning systems ; Integrates with other Nest products

Expensive - even more so as a multi-room system ; Occasional issues with WiFi connection

Nest Protect is certainly a powerful and flexible bit of kit. You might wonder why you need a smoke alarm with so many bells and whistles, but when you realise what it can do it soon becomes clear why it's worth it.

At $119, the Nest Protect isn’t cheap, but pricier options are out there. In this case, though, the outlay is worth it.

If you live in a small enough home where just one smoke alarm will suffice, the Nest Protect is a great choice. It gets very expensive if you need multiple alarms (typically one per floor), but they do work well together and have some useful features,...

The new Nest Protect has a more refined design than the original model, as well a handy in-app alarm silence feature to go along with its already useful connected features and integration with other Nest products and IFTTT.

No other smoke and carbon monoxide detectors available today can match the second-gen Nest Protect in terms of looks and options, making it a great buy for anyone who appreciates design and connected features.
