At $100, the Nest Protect is one of the most expensive, but also one of the most comprehensive, of the smart smoke detectors we've tested.

There’s no getting away from the fact that it’s expensive, however.

It's an expensive bit of kit though – so you're probably wondering if it's worth the outlay and if all the bells and whistles are worthwhile.

Unfortunately, the device warranty is only two years, unlike the 10-year warranties of the First Alert Onelink and Kidde KN-COSM-B-RF.

The Nest Protect didn’t perform as well as some of its competitors in terms of responsiveness, taking 30 seconds or more after the alarm sounded to send notifications.

It has one other thing in common with the Learning Thermostat in that it carries a hefty price tag; at $129 (direct) it's significantly more expensive than what you'll pay for a typical smoke/CO alarm.

The light bulb integrations weren't responsive enough for short smoke events, typically flashing several minutes after our test smoke dissipated.
