“Bought one of these a couple years ago, it worked well for several hundred uses. Eventually stopped registering, though, and when I sent it back for calibration I was told it was beyond repair. I wasn't diligent about regular maintenance, they say it needs calibration every 6 months or so. I think the real problem was using it right after drinking instead of waiting 20 minutes, seems like I burned out the sensor with excessively high readings. I just bought another, they gave me a discount, I plan to follow the directions a bit more closely this time: wait 20 mins before testing, and send back for cal after 6 months.”
“As I mentioned in a review about a month ago (probably through an Amazon request, from which I have now bought 3 devices, for myself & a friend); this is an excellent instrument, up to my scientific standards & is highly accurate. It serves me well and gives me confidence that I have not overindulged in ethanol consumption before driving/riding.”
“This is my second purchase. I bought this one for my son. I don't go anywhere without it, cause ya never know when you might want to pull into a place and check out the beer menu. If you drink and drive, you need this tool. I have learned so much from it. Purchase number three won't be far off. They make great gifts.”
“We have used an S80 Pro for several years now and have found it to be reliable and accurate. I am retired law enforcement, but use our S80 for personal use when we go out with friends and family. We have recommended it to others and recently purchased a 2nd one so we have a spare and coverage for when we send one in for recalibration. Our recent recalibration went smoothly, fast excellent service. Any one who drinks alcohol should have and use a breathalyzer.”
