One Step: 10 x Alcohol Breathalyzer Breath Tester Kit - UK & EU Certified Test Kits

This has been a great purchase to just check next morning that you are safe to drive if you've had a few drinks the night before. I only have to use them occasionally - otherwise it would be too expensive and would then go for a different option. But ideal for occasional use. I even had my guests use them after a celebratory night and as a result of a high reading they stayed for a late brunch to be on the safe side!

Probably ideal for the continent, not really useful for uk driving, ideal for a laugh at a party to see who’s drunk the most, if purple your pissed

It's cheap. I just wanted to get a feel for how long it takes for me to metabolise wine drunk at lunch and the results are about what I'd expect. I don't expect to use it often now I've established that, but from time to time it will be handy. They are dated to last over a year, easy to use, but taking the test and getting a reading takes at least 3 minutes.

These work, better being safe than sorry morning after.

Only 1 year expiry date... If I was knew I would order only 1 or 2. It should be stated somewhere expiry date in add.

Tip Top, just the job

Handy to have. Personally I don't drink alcohol, but my son goes out at weekends. Thought be useful to get nsure he's not over the limit the next day or so. Work well, and almost instant results.

Totally useless. Used the morning after a heavy session. I KNEW I was unsafe to drive cut the crystals remained clear. Also, I had to pierce each end of the tune to break seals. Waste of money 😔
