Alcohol Breathalyser Portable Breath Tester – Compact 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

Got as screct santa gift for some they loved it

Don’t waste your money as this totally unreliable…after a very ‘merry’ night out with friends it showed a reading of zero alcohol less than one hour after my last drink. The only safe way is to not drink at all if considering driving within 24hrs

Fine

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.

The breath alcohol tester is faulty is it possible to send me another one where the batteries go in the spring is missing

Works really well

Easy to use & gives you a reading quite quickly. Don't know whether it's accurate but it's a good guide to let you know whether you should drive or not after drinking alcohol the night before.

Display unreadable ! So I was unable to see if it worked or not. Would not bother with it and the trouble of having to return it.

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.

Good product

I bought this in hopes of monitoring my ketones levels. Several Keto coaches indicated that cheap breathalyzers give enough false positives to keep track of levels of acetone in breath. They specifically said that only "cheap" breathalyzers have this effect due to the technology they use. I should have known that for those swanky youtubers "cheap" means "nothing over $1,000" 😀This device is apparently too cheap: on the first use after several "clearing" runs as recommended by the manual, it screamed "DANGER!" and claimed I have 0.16 BAC. The 5 subsequent uses (over 3 minutes apart, as instructed) yielded 0 BAC. Out of curiosity, I poured myself a double shot of Martell (80 proof cognac). Five minutes later, 0 BAC; Ten minutes, 0 BAC; Fifteen minutes, 1.6 BAC and "DANGER" again. Twenty minutes: 0 BAC.Without being a legal expert, I can tell you that if you use this "device" to check if you're fit to drive, you're looking at an almost certain DUI.

It was made of flimsy plastic and I know it's not calibrated and accurate. Poor quality

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.
