Customer Reviews, including Product Star Ratings help customers to learn more about the product and decide whether it is the right product for them.
To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzed reviews to verify trustworthiness.
it’s a cheap breathalyzer so i should’ve figured it wasn’t going to be the best. it kept reading 0.0 after i had a few drinks. i got it to say 0.3 one time but ever since that it kept reading 0.0. Deffinetly is not accurate & i would spend more money to get a better one.
It’s the cheapest breathalyzer on here for a reason. It always just says 0.0 for BAC, which after a drink or two, is obviously false. I would advise spending $10 more on one that works.
