“After getting my breathalyzer calibrated, after times that I *know* I've had a measurable amount to drink, the breathalyzer is returning '0.0' when I use it. Not sure what happened!”
“The product is great when it is calibrated and working; however, included with the product is the need for an antiquated, expensive, and inefficient process for recalibration needs. If you wait too long, regardless of amount of use, you will need to purchase a new breathalyzer as it is unable to be recalibrated. Ridiculous when other options exist. $25 + shipping every 6 months regardless of amount of use in that time frame is excessive. Plus with time in transit, a person is left without their investment for ~1 month out of a year. Customer service is friendly and the product is great when working. The customer should be aware of what they are signing up for. I'm switching to a fuel cell breathalyzer I can recalibrate at home.”
“I have a couple so I can compare the accuracy. They are about a thousandth (.001)of each other. If you see any swing more than that send it in for calibration. Easy to use and fast.”
