Alcohol Tester, VTIN Breathalyzer with 20 Mouthpieces 【Professional Accurate】 Digital Breath Analyzer Semi-Conductor Sensor Breathaliser - UK, FRANCE

Works well. Easy to use and seems to identify the smallest of traces. In terms of accuracy I can't definitely say as it would need a calibrated measuring device to base line against, however for general use to identify whether alcohol is in your system.... it does that.

Easy to use unless I test it with a police one can not be sure about accuracy

Great product. Would use again

Awful. I tested it when I knew I was over the limit so I knew if I could trust it. It said my alcohol level was 0. I had been drinking alcohol earlier that same night.

Crap

Not sure on readings. As some nights I have had 12 pints, fallen asleep and woken up 4 hours later and it days 0.2% ok to drive ?!?

just doesn't work.. 5 times totally different readings, huge difference between them as well..

Makes driving safer
