“This product is accurate and dependable. My boyfriend and I each got one and feel that we can go out comfortably and ensure that we are legal to drive (or if its time to call an Uber). We each keep one in our car and could not be more pleased with the dependability/accuracy”
“It is still accurate. I test it by having drinks adjusted to my body weight. I drink takes an hour to clear out and two takes two. So I know it is working accurately after 500 uses.”
