Nest Offers Discounted, Wave-Less Smoke Alarm

Nest has returned its Protect smoke and carbon monoxide alarm to the market, less than one month after recalling 440,000 units because of a defect. The device has been discounted to $99 from $130. The Protect was recalled because of a software glitch that could prevent it from properly sounding an alert. Nest issued a temporary software update to disable its Wave feature, promising a permanent fix later. Returning the device to the market before a permanent fix has been developed may call into question Nest products' reliability and quality.
