“I personally own two S80. Always want to have a second for use when the other unit is calibrated. When used one after the other they are both dead on the same reading or have the slightest margin of difference. This year I bought seven Units to give to my friends and family as Christmas gifts. The S80 is an amazing educational tool.”
“I recently had an Ignition interlock device installed in my vehicle for a DUI, BACtrack S80 lets me know every time if I'm OK to drive before I get behind the Wheel. 5 stars”
