Nest Labs’ smoke and carbon monoxide detector, Nest Protect, was recently recalled due to a potential safety issue which meant that the alarm could be unintentionally deactivated.

Jump forward a few months and Nest has resumed sales of the device — fixing the problematic feature via both a hardware and software update. Even better, the units now cost just $99, down from the previous price point of $129.

Nest announced the return of Nest Protect in a blog post, highlighting the “real-life story” of a thankful Nest Protect user named Lucas Wollermann:

“We’re very pleased that Nest Protect is once again available to customers. And now, the price is $99 to make it accessible to as many people as possible. Because we want to see more CO emergencies end up the way Lucas Wollermann’s did.”

Nest has also updated its companion mobile apps, with improvements to Nest Protect account pairing.

Having removed a feature which let users deactivate the smoke detector with a simple wave, Nest Protect now requires users to press a hardware button to turn off the alarm.

Nest Protect was the second product released by Nest, following its flagship product, the Nest Learning Thermostat. Google acquired the company in January this year for a hefty $3.2 billion.
