Very Accurate!
I have another brand pocket breathalyzer, and this one seems to give a much more consistent and accurate reading compared to the other unit. I love the estimated time to sobriety as well, it's a cool function. This device is small enough to keep in a side door, glove box, or anywhere in your car, so if bars ever open up again, I highly recommend getting one of these to make sure you are good to drive. This could definitely save lives.
