2-Pack Haven Detector©

Really like the digital information provided, temp, Ppm, and relative humidity. Simple plug and play and easy to check as you walk by.

Product recieved was the newest version which was an unexpected surprise when I opened the package. The card noting that the company took the liberty to upgrade to a new model based on the timing of its release was well received. Product auto set up and calibrated as expected and leavese comfortable to know my family is protected with a quality product from a company with integrity.

Too way long to get here. Plugged them in . They seem to be doing what they promised. No alarms yet.
