“The original key chain model was better. It was more reliable and the calibration lasted much longer. This latest model is less accurate and requires constant calibration which is at a cost that you might as well buy a new one making calibration futile. There are other manufacturers who offer breathalyzers that do not require calibration which is a better way to go.”
Hi John,
I appreciate you sharing this feedback. The keychain model you mentioned was designed differently, which is why it felt lower-maintenance possibly. The current model uses a sensor with increased sensitivity to produce a higher degree of accuracy, and that sensitivity means regular calibration is necessary to keep results reliable and the extend the life of the unit. While calibration does carry a cost, it ensures the unit continues performing correctly over time. We understand some manufacturers market ‘no-calibration’ devices, but those typically rely on less precise, minimally tested technology. Our goal is to balance convenience with accuracy, since accurate readings are what matter most for safety and compliance.

“I won’t leave home without it! Not only is it fun, but always keep me safe and conscience of my BAC. It comes with multiple mouth pieces so you can share with a friend, too. This little gadget is a game changer for sure and provides me and my loved ones with peace of mind every time I go for drinks.”
