Getting a DUI? Bad.

With risks this high, investing in a portable breathalyzer isn’t just smart—it could be lifesaving.
That’s why I tested the top 5 personal breathalyzers to see which one truly protects you from a bad decision.
Some were good, others not so much, but one stood out above the rest.

It’s non-contact, features an HD display, and has a long battery life, making it ideal for quick and hygienic breath tests. Its one-button operation and USB charging add to the convenience.
Durability and Convenience: Its lightweight and portable design, combined with long-lasting battery life, make it easy to carry and reliable for frequent use. Plus, with a 50% discount and bundle offers, it’s a great value for a high-performing breathalyzer. Due to its popularity, it frequently sells out.

from BACtrack
Precision and Features: BACtrack Go is portable and provides quick results, plus it comes with a keychain for convenience. However, the readings can be inconsistent, sometimes displaying 0.00 BAC when alcohol has been consumed, making it less reliable than the Breath Guard Buddy.
Durability and Convenience: While easy to use and portable, BACtrack Go doesn’t last as long as advertised and has reported issues with inconsistent readings over time.
Verdict: BACtrack Go is useful for casual, portable use, but Breath Guard Buddy offers far more accurate and reliable results, making it a better long-term investment.
from BACtrack
Precision and Features: BACtrack S80 provides reliable readings with quick results and a simple one-year warranty. However, it’s pricey compared to the Breath Guard Buddy, and it requires recalibration every 6-12 months, which adds to maintenance costs.
Durability and Convenience: Though it’s reliable, BACtrack S80 lacks the ease of use and affordability of the Breath Guard Buddy, especially given its high price point and the need for regular recalibration.
Verdict: BACtrack S80 is great for users who need long-term reliability, but Breath Guard Buddy provides similar accuracy at a fraction of the cost, with more user-friendly features.
from Rofeer
Precision and Features: Rofeer’s digital breathalyzer offers features like sound warnings and color distinctions with six measurement units. However, you need to wait at least 20 minutes after your last drink to get an accurate result, and the results can vary. Additionally, replacement mouthpieces are hard to find.
Durability and Convenience: While budget-friendly, Rofeer’s inconsistency and difficulty in finding parts make it less convenient than the Breath Guard Buddy, which offers more reliable results and easier usability.
Verdict: Rofeer is a good low-cost option, but if you need accuracy and convenience, Breath Guard Buddy is a much better choice.
from iSOBER
Precision and Features: iSOBER 10 meets NHTSA requirements and connects to an app that can send information to family and friends. However, it struggles with Bluetooth connection issues and poor battery life, making it less reliable than the Breath Guard Buddy.
Durability and Convenience: The app feature is handy, but connectivity problems and a costly price tag make it less appealing. Breath Guard Buddy, on the other hand, offers longer battery life and simpler functionality at a lower cost.
Verdict: iSOBER 10 is a more advanced option, but for everyday use with reliable accuracy and portability, Breath Guard Buddy is the smarter and more affordable choice.
