“I purchased this model recently, to replace the same model from a few years ago. I purchased it because it worked well before, and it was easy to use for the residential facility that I purchased it for.”
“I keep mine in my vehicle to use as a gauge when I'm out socially and have a couple of drinks. My S50 is compact, discreet, easy to use and takes ~2 minutes to get a test result. Fits my needs perfectly at reasonable cost.”
“As advertised the BACtrack Select S50 has a "Three digit display shows BAC test results in easily recognizable format from 0.00 to 0.40 %BAC." The first digit is always a "0" and is useless. The "Three digit" discription is accurate but I would rather have the third digit at the other end.”
“THIS PRODUCT IS VERY USEFUL TO MAKE SURE THE AVERAGE PERSON IS SAFE TO DRIVE, HOWEVER, IT CAN NOT BE RELIED ON FOR ACCURATE RESULTS IF YOU FIND YOURSELF WITH AN INTERLOCK DEVICE ON YOUR VEHICLE. THE INTERLOCK DEVICES INSTALLED (FOR LEGAL PURPOSES) HAVE A MUCH FINER "EYE" FOR ANY TRACES OF ALCOHOL. I ADVISE WAITING ANOTHER HOUR ONCE THE BACTRACK REGISTERS "0.00" BEFORE STARTING ANY VEHICLE EQUIPPED WITH AN INTERLOCK DEVICE. I'VE SEEN SEVERAL FAILED TESTS WITH THE LEGAL EQUIPMENT WHEN THE BACTRACK REGISTERED ZERO CONTENT. IT IS MARKETED AS A GUIDE, AND SHOULD BE USED AS SUCH.”
