4x Google Nest Protect Smoke and Carbon Monoxide Alarm (2nd Gen)

Selling a set of 4 Google Nest Protects. These are the 2nd gen models that do both smoke and carbon monoxide. They're super handy because they actually talk to you and tell you where the smoke is instead of just beeping like crazy. You can also hush them from your phone if you just burnt some toast. They're used but in good shape and come with the mounting plates. Great way to smarten up the house safety.
