## At a glance

- Use it with standalone results on the device or wirelessly with the BACtrack smartphone app.
- The listing describes a BluFire fuel-cell sensor and a ZeroLine estimate of when BAC may return to 0.00%.
- Small form factor is described as suitable for a pocket, purse or keychain.

## Before you buy

- Breathalyzer readings and the ZeroLine estimate are not guarantees of fitness to drive. Customer feedback is mixed on accuracy, and the listing says periodic recalibration is required, with additional charges. Follow the manual and do not use an estimate as a substitute for safe transport decisions.

## A good fit for

- Buyers seeking a compact breathalyzer with on-device results and optional smartphone connectivity.
- People who want a portable device with an estimated time until BAC returns to 0.00%.

## Less suited to

- Buyers seeking a device that needs no periodic recalibration.
- Anyone treating a breathalyzer result or estimated return time as proof that driving is safe.

## Customer feedback

Customer feedback describes the device as easy to use, practical and conveniently small, with positive comments about connectivity. Concerns about durability and mixed views on accuracy and value matter because this is a portable measuring device whose results require periodic recalibration. Ratings are mostly five-star, but a notable one-star share signals that experiences are not uniformly positive.
- Positive themes: Customers describe it as easy to use and practical, and speak positively about its size and connectivity.
- Negative themes: Customer feedback includes concerns about durability.
- Mixed feedback: Customer views are mixed on accuracy and value for money.
