Alcohol Breathalyzer Portable Breath Tester - Amacam AT-01 Accurate Digital Display Convenient Lightweight Pocket Design A Must if You Drive the Next Day after a Night out Drinking. Be Safe Not Sorry.

Works well for detecting alcohol in fermentation experiments.

The media could not be loaded.  I have tried it numerous times and it keeps giving me a reading of zero. I’ve literally taken a step and blown into it with alcohol freshly in my mouth and it’s still giving me a zero I have been drinking I want to say for about two hours no plans of going anywhere but I just wanted to try it out. I’ve had about seven cosmos at this point each one had about three shots of vodka and it’s still reading at zero.

I bought this a few months ago. It worked at first but after a few months of not using it it won’t register I’m blowing more times than not. I warmed it up between 10-15 times and the same thing. It’s not registering I’m blowing at all more times than not. It’ll work about 1-2 times out of every 10 warm ups now. When it does work it’s seems semi accurate but it’ll show I’m at .07 after one half shot with orange juice in a 8 ounce cup and there is no way I could blow that high after one drink like that. Then I do a second drink of the same thing and it’ll be down at a .04 or .05 which makes no sense that i would blow higher on the first one than the second one. Even the next day it’ll say I blow a .03 and I’ve even done it 2 days since I had any alcohol and it reads the same .03 which there’s no way that’s possible. If only it wasn’t past the time to return it or exchange it I would be for a different one.

I tested positive for ketones once, then never again. Maybe I just never got into ketosis again. It did register alcohol reasonably well, I really don't know about the accuracy but my friend got a positive reading after one beer.

The breathalyzer’s portable design makes it easy to carry with you wherever you go. Its user-friendly interface and simple operation allow for quick and accurate BAC readings. Just breathe into the device, and within seconds, it displays your estimated BAC level on the screen.The accuracy of the breathalyzer is crucial, and while it may not be as precise as professional-grade devices used by law enforcement, it provides a reliable estimate of your alcohol level. It’s important to note that the results may vary based on factors like metabolism and recent consumption, so it’s always wise to use these devices as a general guide rather than a definitive measure of intoxication.

I bought five of these and two of them simply don't work. It only gets two stars because testing five breathalyzers at once was actually quite fun!

It reads at zero ever single time no matter how much I’ve been drinking. This is honestly a dollar store quality item. The plastic is super cheap and you can see it breaking at the seams. Wouldn’t buy again.

A good simple product that works as expected and fits well and is easy to use.

Works really well

Good product

Bought one some years ago. Worked very well for a long time before giving up the ghost.So bought this (almost identical) replacement. Doesn't work. Even if you are swirling whiskey in your mouth, gives you a zero reading.Binned it.

Fine

This product is not accurate and doesn’t work , I would not drive after the beers I had and it wa so my reading 0.2 which 0.7 is the limit , there completely unaccurate
