AlcoSense EXCEL & PRO BREATHALYSERS - Peace of Mind to Know You are Safe to Drive the Morning After.


TOPCAR Product rating *****

  • Accurate, quick and simple breathalyser’s that check if it is safe to drive the “morning after.”

  • An ideal personal gift or device to share amongst the family.

  • A sensible investment to protect your driving license, job and more.


As a young driver, now aged 19 (still a teenager), you are constantly reminded that driving a car is a huge responsibility. And it is.

When you drive you are responsible for your own and the safety of others around you. This is why following and understanding the various laws and road safety rules is critical. Not drink driving is one of the most important rules.

The official advice to all drivers is not to drink and drive. Statistics show in the UK that over 3000 people are killed or seriously injured seriously injured due to drink drivers. Over 5500 people fail the drinking test the morning after and the consequences can cost £50,000 of lost income, your job and result in a criminal record.

Thanks to Alcosense I was given the opportunity to review their Excel and Pro breathalyser’s. Reviewing these will involve a mixture of online research and practical testing (obviously with no driving). Alcosense produce a wide range of personal breathalyser devices that aid law-abiding drivers to avoid the risks and disasters associated with drink driving. The simplest is a single use devise costing £2.99 to £250 for the “Ultra” model.


- Clear Display, Really Easy To Use -

As a young designer, first impressions of products count. The Excel and Pro breathalysers are cleanly designed, well-built and robust products. Importantly the instructions are clear and simple to setup either device. The Excel is the first breathalyser under £100 to feature a full colour screen and intuitive graphic user interface giving on-screen prompts and tips. The Pro version, costing £149.99, offers even greater accuracy, a database of all drink drive limits worldwide,  Blow-Coach and Time until Sober & Retest alarm.


At the heart of two units are respectively a 64mm2 or 121mm² professional fuel cell sensor to detect alcohol in your breath, which is the same technology as used in police roadside breathalysers and highly accurate.

Pro by name, pro by nature. It uses a 121mm² professional Fuel Cell sensor

To familiarise myself with the products involved a family outing to the local curry house, to have a few Tikka Masalas and a few glasses of wine and beer. Once we had let the food and alcohol to settle, we tested both devices.

Both devises provide simple colour coded results with a RED-AMBER-GREEN display, that reflect different alcohol levels. The Pro version has a Blow-Coach display that shows if you are blowing too soft or hard to get an accurate reading. In addition, the display shows the Time Until Sober reading.

Me the designated driver with zero


The results from each device are very similar, as to be expected. It highlighted how different people respond to alcohol. Only the designated driver was safe to drive!

Having a breathalyser in the house was interesting as it brings the topics of drink driving and the effects of alcohol into conversations with family and friends. Everyone was very impressed with the breathalysers; the sobering time was an eye opener!

Whether it’d be a family meal, night out or a few drinks after work, unintentional drink driving the morning after is easier than you might think. Drinking 4 pints between 9pm and midnight could mean you still have alcohol in your system at 11am the next day, that is why most accidents happen the morning after, according to the Department for Transport (DfT). One in five drivers found drink-driving, are caught the morning after.


The only drawback with the two units is the need an annual recalibration which costs £24.99. However, for all drivers the AlcoSense products aids responsible and safe driving.

In summary, the Excel and Pro breathalysers are two excellent products. The £100 Excel offers great price for performance. The extra accuracy and features of the Pro version will justify for many the additional £50. I fully recommend these 5-star breathalysers to give peace of mind to know you are safe to drive the morning after and avoid the consequences listed below.
