### ⭐⭐⭐⭐⭐ 







  
  
    Great sobriety tool and worth the price
  

*by S***H on Reviewed in the United States on 7 September 2022*

We bought this product as a means of rebuilding trust after a relapse with alcohol and it has worked extremely well. Any time there is a question of sobriety, just grab the device and within 20 seconds you’ve got your answer. As far as I know it is accurate and is easy to use. I would recommend this to anyone looking to give or get piece of mind in a situation regarding maintaining sobriety.There are other devices that are cheaper but I think you are really getting a solid product here.

    Used as measure before / during night out & Pulled over RBT Same night
  

*by K***R on Reviewed in Australia on 2 October 2022*

Drank and measured .27 - waited two and half hours, blew .00 - waited an extra 30 minutes before driving just in case. Pulled over for RBT (Aus) not long after, blew zero again. Good product. Safety first!

    Better safe than sorry!
  

*by J***E on Reviewed in the United States on 27 October 2020*

I purchased this product to replace one I'd received as a gift that I've apparently lost in the ensuing years. It's useful to have a breathalyzer at home when you have company over just to forestall any guests' arguments of "But I feel fine to drive!" While we don't have many people over these days due to the pandemic, my parents do stop by after I've gotten a negative COVID-19 test and frequently have a glass of wine or a beer with dinner. Lately they've been expressing feeling the effects of even a single drink, so I decided it's time to invest in a new breathalyzer to see if they've just become lightweights during quarantine or if they're actually becoming impaired from one drink. Better safe than sorry!While I certainly don't have bloodwork to compare this to for accuracy, based on my preliminary testing, it is providing the readings I would expect so I'm happy so far. Both my partner and I have tested this without consuming any alcohol, and both got the anticipated 0.00 reading, and after a drink or two. For example, about half an hour after drinking a small glass of wine, I got 0.027 (which is about what I'd expect).I don't tend to drink a lot more than a glass or two in an evening, so I haven't tested it at higher B.A.C. levels, but the lower end results give me confidence in this device's accuracy. I am pleased with how quickly this gives readings and how easy it is to use. You don't have to blow out all your air for it to work, which is nice. The kit includes enough mouthpieces for several people and they seem durable enough that I could clean them and reuse them. I also received a card in the box for a prize with my purchase (haven't checked it out, so not sure what it is!), which was an unexpected bonus.Now to the caveats: as with most any breathalyzer, you have to wait 20 minutes after eating or drinking for accurate results. It's kind of inconvenient, but even the small keychain breathalyzer I had years ago had the same requirement, so it's par for the course. The more important thing to keep in mind is that if someone SEEMS too impaired to drive, they ARE! Some people can be more impacted by the effects of alcohol than others, even in low doses, and you can get a DUI with a B.A.C. below 0.08. I would never use this as the only factor determining if someone is safe to drive! However, I like to have one at home in case someone insists they're OK to drive and refuses to listen to reason. It's harder to argue with a breathalyzer!I'll test this product again next time I have guests or if anyone drinks more than what we've already tested and will update my review accordingly if I find the results to be less accurate then, but for now, I'm happy to recommend this product for someone looking for the extra peace of mind when drinking or letting guests drive home. I'd still encourage you to use your best judgement even with low range results, and if in doubt, don't drive!
