Omiva Model 1 is a portable breathalyser listing that claims semiconductor sensing, simple operation and up to 45 days of battery use.

What to know before buying

Listing details to confirm

The listing is inconsistent about battery life, claiming up to 45 days in the feature text but 30 days in the title. It also calls the sensor technology US AIS without defining the term, claims up to 99.99% accuracy without specifying how it is measured, and gives no measurement range, units or result format. Confirm these details before buying and do not rely on an unspecified consumer tester to determine whether it is safe or legal to drive.

Who is it for?

A good fit for

People seeking a lightweight personal breathalyser for occasional self-checks or travel.
Buyers comfortable with an unspecified measurement scale and resolving battery and performance claims before purchase.

Less suited to

Anyone needing documented accuracy, a stated measurement range or clearly specified units.
Anyone relying on a personal breathalyser to establish fitness to drive or legal compliance.

Aggregate ratings lean towards the four-star category, with some three-star ratings and fewer five-star ratings. This is a small rating sample and includes no written feedback, so it does not establish customer-reported strengths or explain the mixed scores. Buyers should weigh that limited evidence against the listing's unresolved battery and measurement details.

Frequently asked questions

How long does the battery last?

The listing is contradictory: its title says 30 days, while the feature text claims up to 45 days. Confirm the applicable runtime with the seller.

What result does it display?

The listing says to read the result but does not specify its format, units or measurement range.

Is the claimed accuracy independently established?

No independent verification is supplied. The up to 99.99% figure is a listing claim with no stated measurement conditions.

Can this determine whether I am safe to drive?

Do not rely on an unspecified personal tester to establish fitness to drive. The listing does not provide a measurement scale or supporting accuracy details.
