“I love the size, utility, and (specified) accuracy. It's my only breathalyzer so it's hard to give a definitive "accuracy" but based on my understanding it seems in line with my expectations. It helps me calibrate my understanding of how drunk I can get after a night out and make smarter decisions given the context that I find myself in.
Just be sure to follow the directions of "don't blow before 20 minutes after your last drink." Just for fun I blew right after a shot of fireball and got it up to 0.4!”
“Has worked perfectly so far, exactly as advertised, had it for a couple of months.
I chose this model over others for its smaller size while still having specified accuracy, plus memory was a bonus.
I bought 2 of them, keeping one for infrequent use. Then we can compare periodically to know when the heavily used one needs re-calibration (or not).”
