What owners report

Known issues and safety
Recall check: we searched GOV.UK product safety alerts, reports and recalls (Office for Product Safety and Standards) for “alcosense” and “breathalyser” on 19 October 2026 and found no results for either [2]. Check the list again for the exact model.
The maker lists no test memory and a 5-minute gap between tests [1]. Alcohol levels can keep rising after your last drink, so a low reading soon after drinking does not mean you are safe to drive.
Questions people ask
How accurate is it?
AlcoSense states ±0.20‰ BAC at the limit [1]. That is a wide margin, so do not use it to decide whether you are just under the limit.
Does it need recalibrating?
Yes, every 12 months or 300 tests, at £22.99 including VAT [1].
Can I set a different drink-drive limit?
Yes, to the UK, Irish and Scottish limits [1].
