Breathalyzer, Professional Breath Alcohol Tester, Portable Digital Alcohol Detector LCD Screen with 5 Mouthpieces, Auto Power Off and Sound Alarm - Black Upgrade

This breathalyzer is perfect. It works really well. I checked with 4 different ppl at the same time. 1 didn't drink at all. 1 drake 2 beers. 1 drank 3 shots and last one drank 4 beers. The number was similar to the chart online based on their weights. Perfect.

Tested it out after 1 beer. After 10 tries I didn't get a single accurate reading. Went from as low as 0.01% to as high as 0.14%. After 1 beer. Really disappointed in this product. Best to just shovel out the extra money and get a better one.

Product does not give an accurate reading at all. It says either 0.000 when you had only a bit of alcohol. If you had drank anymore than a beer it reads 0.200 [!!DANGER!!] and beeps loud for 30 seconds.I have tested it around 100 individual blows and the only readings I received are 0.000 and 0.200 (death I assume). If you actually blow a 0.200 its puke coming out, not air.Beware that this product has NO REVIEWS. It did when I purchased it (several hundred) and when I checked my order history it was no longer available and was listed as a new item by the same seller.If you are purchasing this as a safety device BUY the BACtrack (Cost ~$130) and is available here on Amazon!I never leave negative feedback, but this is a SAFETY device and gives a poor reading. I must post this for those who are going to trust this device for their safety or the safety of a family member.Spend the money on the better one please if you are going to trust one of these devices. The BACtrack is MUCH better.

First of all, this breathalyzer came out of the box reading the air .04 . I gave it some time to calibrate, and next time I drank about 4 beers, online BAC calculator based on gender and weight gave me an estimated .07. I was unsure about driving, so I consulted this piece of garbage, and gained a reading of .03!what?I believe these reviews are faked, don't risk it

 Between open-bar work parties and getting through visits with grating family members, it's hard to blame anyone for wanting to throw back a few drinks to take the edge off during the holidays. Unfortunately, we cannot always tell if we are in good enough condition to get behind the wheel of a car. Thankfully, there are a number of top-quality personal breathalyzers available to help you avoid driving under the influence (DUI).Before I begin talking about my personal breathalyzer pick, it is important to note some limitations. First of all, and most importantly, your ability to drive is completely unrelated to a BAC number. If you feel impaired, you should not drive. Period.On the other hand, if you feel perfectly okay to drive, you should wait at least half an hour after you last eat or drink anything before testing your BAC because your BAC can increase even after you stop drinking since your body keeps absorbing alcohol. If you still do not feel impaired, then a breathalyzer can provide you an objective measurement of whether you can legally drive or not.That said, the breathalyzers on the market these days vary wildly in their accuracy and reliability. For the most part, you do get what you pay for. The more expensive models tend to be more accurate. But, as you have heard from countless news stories, even the best devices used by law enforcement officers can register false positives.That is interesting to know how a breathalyzer works, so I searched I found out and I am sharing with you:A breathalyzer is able to work because of the way the body processes alcohol.--Alcohol is absorbed into the bloodstream from the stomach, intestines, and mouth. The alcohol molecules do not change during this absorption process. The blood then carries these molecules throughout the body.--The molecules eventually reach the lungs and are expelled as the person exhales. This is why you’re often able to tell whether someone has been drinking by the smell of their breath. Alcohol molecules add a distinctive odor to the breath.--The concentration of alcohol in the lungs closely matches its concentration in the bloodstream. So by measuring alcohol concentration when a person exhales, the breathalyzer is able to provide a relatively accurate BAC number.I think this breathalyzer is mid-range personal breathalyzer which is easy to use, although BAC accuracy is hit-and-miss.Please click on helpful if you think it really was.

Excellent product for a great price
