After two months off the market, Google Nest is back and ready for purchase, but it won't have the Wave feature after security issues arose over its faulty trigger system.

The smoke detector and carbon monoxide detector has also seen a drop in price to $99, cutting $30 off the original $129 price tag.

The Wave feature, which had allowed users to move their hand in front of the device to silence the alarm, had not been functioning as designed so it has been disabled.

Nest Protect has since updated the software to disable the function completely and has also given owners the opportunity to return the product for a full refund if they desire.

A company spokesperson was quoted by TechCrunch as saying that Nest is currently shipping with the function disabled and they were also "still looking into a solution."

The past few months of controversy surrounding Nest has left many observers questioning the company and its efforts to rectify any problems that arise, especially considering Nest had promoted the Wave feature in its launch as an innovative and unique option for home owners.

Google acquired Nest for $3.2 billion and hopes that the new addition to the Google family will deliver safety inside homes.

However, concerns arose in early April in lab testing over the safety of the Wave feature, which let users turn off the alarm with a wave of their hands. Nest co-founder and CEO Tony Fadell said at the time the company was making every effort to ensure the safety of its products. He hoped that the situation would be under control so Google Nest could continue to provide home security solutions.

"We observed a unique combination of circumstances that caused us to question whether the Nest Wave could be unintentionally activated. This could delay an alarm going off if there was a real fire," he said. "The fact that it could even potentially happen is extremely important to me and I want to address it immediately."

Google has officially not commented on Nest's recall, nor its return to the market, instead referring all media inquiries to Nest, which has repeatedly said it was inundated with questions, but would answer "all related concerns to the public and the media as they become available."
