⚖️ Overall Quality & Impressions ⚖️ ● Well-constructed and easy to use. ● Works as expected. I don't really have anything to compare it to, but the testing I've done so far accurately reflects how impaired I think I am, which is reassuring. ● The mouthpieces are great. I expected them to be disposable, flimsy plastic, but they feel almost like glass and are quite sturdy. It's great that they can be washed and reused. ● Comes with a handy pouch that makes for easy storage in my car.

    I bought this Breathalyzer Alcohol Tester from 鶹 a few weeks ago and I am very satisfied with the results after having a few alcohol beverages. It is quite accurate and gives you peace of mind of testing before driving. I have tried others and I had to return because of the inaccuracy. Also, I tried it with my family and friends and they are quite impressed with the quality and accuracy. They will be ordering from this seller. The seller has reached out to me if there is any issue, don't hesitate to contact him. That's excellent customer service and I highly recommend this product.

    5.0 out of 5 stars Time to have safe parties at home
    Reviewed in the United States on July 7, 2024
    Verified Purchase
    There are a few reasons why someone might choose to have this portable breathalyzer at home:

    This breathalyzer can help people understand how alcohol affects their Blood Alcohol Content (BAC). This can help them make informed decisions about driving or operating machinery after drinking.

    Having a breathalyzer at home can serve as a deterrent to drunk driving. If someone coming to your party knows they have a way to test their BAC level, they may be less likely to take the risk of driving under the influence.

    For people who are trying to cut back on their drinking, a breathalyzer can be a helpful tool for monitoring their consumption.

    However, it is important to remember that breathalyzers are not perfect. They can vary in accuracy, and they should not be used as a sole method for determining whether or not someone is safe to drive.

    Keep in mind that, although the device seems to work as intended, it may not be as accurate as a police-grade breathalyzers.

    Ich bin sehr zufrieden mit diesem digitalen Alkoholtester. Die Bedienung ist kinderleicht, einfach einschalten, pusten, und innerhalb weniger Sekunden erscheint ein klar lesbares Ergebnis auf dem Display. Besonders praktisch finde ich die mitgelieferten Mehrweg-Aufsätze, die eine hygienische Nutzung ermöglichen, auch wenn mehrere Personen testen wollen. Das Gerät wirkt hochwertig verarbeitet und liegt gut in der Hand. Die Messwerte erscheinen plausibel und konsistent, was Vertrauen in die Genauigkeit schafft. Ideal ist es für private Zwecke, z. B. nach Feiern, um sicherzugehen, ob man noch fahrtüchtig ist. Ich kann es allen empfehlen, die schnell und zuverlässig ihren Promillewert prüfen möchten ohne komplizierte Technik.

    J'ai testé cet éthylotest sur plusieurs heures après avoir consommé 2 verres d'alcool puis un troisième 1/2 heure après puis un quatrième 1 heure après.
    J'ai attendu 20 minutes après la dernière consommation et j'ai soufflé dans l'éthylotest.
    Le résultat est bluffant.
    Les mesures indiquaient 0,3 gr puis 0,4 gr après 30 mn pour finir à 0,5 gr.
    Après 60 minutes c'est redescendu à 0,10 gr pour être à 0 trois heures plus tard.
    Le résultat permets de se faire une idée pour ne pas prendre la volant.
    Je recommande vivement cet appareil
