BEAUDENS Personal Breathalyzer Professional Alcohol Breath Tester with Accurate and Fast Results

Seems to do the job pretty well. Multiple takes read the same or very similar results. I would always blow twice to make sure anyway. As with an breathalyzer the longer you wait the more accurate the read, so taking within a few minutes of a drink will give you a false high read.

Decided to do a test . I found the test results very erratic. After drinking 4 cans of larger at 4% its results were first 30mins over the limit then the odd test saying I was below the limit and drinking coffee completely made it pass, . After 1hr it was saying all clear to drive then 2hrs showing no signs of drinking at all. I'm not trusting this device to be accurate. But worth a try. Think you need to spend a lot more money to get a reliable one or just dont drink.....

To try this out I had a pint of 4% lager, followed instructions and it told me there was no alcohol detected. Continued to test it and it was still saying I was ok to drive after 5 pints. Doesn't seem very accurate to me. Told I'd receive refund in 2 days and it's now over a week later

Exactly what I was looking for....value, quality and ease of use. It has been very reliable and conveniently portable

Bought this for my husband just to be sure he is safe to drive in the morning after drinking . It's a brilliant little gadget, very compact, portable and easy to use.

Very useful for me and my boyfriend . I could check him at anytime before driving.Make me more happy with my boyfriend

Easy to use. After going out one night I tried it with my friends and it worked they came up red and i came up green!

Seems to be consistent in that two bottles of strong ale takes me over the limit. Don't know how that compares to the breathalysers the police use but I use this one and any indication of a percentage of alcohol I don't drive until it's zero percent.
