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,...

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

It has numerous features including smartphone connectivity and safety lights that can guide your way to safety in a dark or smoky environment.

The manufacturer warranty is only for two years.

The Nest Protect 2nd Gen wireless smoke detector boasts a number of impressive features, but its brief warranty period of two years means it may need early replacement.

Exceptionally smart ; Easy to install ; Works brilliantly

Expensive

The Nest Protect is the smartest smoke detector you can buy – and the least annoying; but it's quite expensive

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.

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.

The history section in the app is empty and it doesn't have enough new features to justify an upgrade from the original.

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.
