## Customer Reviews

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Useful, consistent and well priced
  

*by Z***H on Reviewed in the United States on October 26, 2022*

Give this breathalyzer five stars because it's solid, does its job, and doesn't try and do too much. Of course, stuff like this on Amazon always tries to do too much, but this keeps it simple and does it well. One note I've seen in other reviews that I'd like to reiterate is that this doesn't ship with the necessary 2 AAA batteries, but at the price point it's at its perfectly fine.

### ⭐ 1.0 out of 5 stars







  
  
    Not accurate
  

*by K***0 on Reviewed in the United States on April 24, 2023*

This item does not give an accurate reading. Had it tested by a friend who is a police officer and 2 out of 3 times the reading was zero when the police breathalyzer showed close to the legal limit. Waste of money.

### ⭐⭐⭐ 3.0 out of 5 stars







  
  
    Not At All Discreet
  

*by P***N on Reviewed in the United States on September 26, 2022*

It’s almost a really good little device, EXCEPT it beeps loudly if it registers .02 BAC and above, which makes it completely useless in a public setting. I would understand if the alarm went off when you were close to .08, but if you’ve had even a single drink and want to be safe before heading home, you’re going to draw the attention of the entire restaurant with this thing. As far as I can tell there’s no way to turn off the sound. If there were this would be great, but as it is this thing is kinda “meh.”
