BACtrack uses carefully-engineered technology to deliver reliable, consistent BAC results, with unparalleled accuracy. Several independent agencies have tested popular personal breathalyzer brands and found BACtrack to be the most accurate. How often do BACtrack breathalyzers need to be calibrated? Our general recommendation is to have your BACtrack calibrated every 12 months, but it really depends on how your BACtrack is performing.

Great product to have if you have had a few drinks and want to know if you're okay to drive. ### ⭐⭐⭐⭐ NOT 100% SURE OF RELIABILITY *by on Reviewed in the United States November 19, 2025* I have used it once with mixed results, first test result was 0.05 BAC and the 2nd about 40 minutes later after finishing a glass of wine, though also drank a lot of water, result was 0.03% BAC. Will need to try when at home after a few drinks to see if results are within range. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.ar/products/17474234-keychain-breathalyzer-portable-bac-alcohol-tester-blue](https://www.desertcart.com.ar/products/17474234-keychain-breathalyzer-portable-bac-alcohol-tester-blue) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-11-11*
