Professional Digital Breathalyzer, Portable Breath Alcohol Detector LCD Display Alcohol Tester with 10 Mouthpieces

Very simple device to set up and use. The five extra mouthpieces are handy. That the voice seems to be very accurate. It also comes with a nice storage bag.

I bought this item a few weeks ago. Jumps from 10 second to 5 second blow into mouth piece and always has same reading. Don’t rely on it. Should have paid more for a better quality device.

Testing only

Seems to be accurate and is easy to use.

After a night of drinking I woke up with the taste of alcohol in my mouth. used the breathalyser and it read okay to drink. but I didn't trust it so its hard to say whether it works or not. it did read warning when I tried it after a drink. so I don't know.

The product works and reassured me before I set off on a journey the morning after.

Excellent product

poor. arrived today and tested it by having a beer and taking multiple breath tests, got wildly varying readings from under the limit to 3x over!!!! . Seems to be completely unreliable.
