What to know before buying

The listing describes disposable chemical testers, not a reusable digital device. Follow the supplied instructions and do not treat a result as assurance that it is safe or legal to drive.

Travellers who prefer a compact single-use test rather than carrying a reusable electronic breathalyser.

Anyone looking for a substitute for official legal guidance or a reliable determination that they are fit to drive.

Customer feedback describes the product positively for quality, value and travel use in France, and reports appreciation for its functionality and fit. Reported shelf life is mixed, with feedback citing examples from 5 months to around 18 months. That variability matters for a disposable kit intended to be carried ahead of a trip, so check the expiry date on the supplied units. The listing describes a two-test pack and a colour-change process, but these product claims do not establish customer experiences or independently confirm certification.

How does the tester work?

The listing describes blowing into a supplied bag, attaching the tester tube and squeezing the air through it. It says crystals change colour in the presence of alcohol and claims results in 2 minutes.

Is this a reusable digital breathalyser?
