“I chk my BAC before starting my vehicle.There are many substances that will alarm my interlock device.Pickles,tangerine,energy drinks,peppermint the lidt gies on.The s80 gives me piece of mind I won't incure a $45 lock out.My plan is to have a second unit,when mine goes out for calibration when necessary. Money well spent”
“I use this whenever I am drinking at different stages and the results are very consistent to the extent I can accurately predict the reading depending on how many beers I have had”
