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

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.

Bought in case we needed them in France.

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.

This is for work which we have not used as of yet however, our work force know we have them so maybe a good deterrent

The image makes the crystals look more orange than they do in real life, it’s honestly some shade of pink to the actual eye. Test is definitely down to judgement, but ok for a rough indication of whether there’s been a significant colour change. Of course without an actual calibrated breathalyser to use at the same time, you’ll never know the true accuracy of this product for yourself.

Easy to use.

I tested this the night I had a drink and there was no change in the colour, checked the following morning to see if I was safe to drive and according to the test again, I was safe to drive, all 4 tests showed no change in colour.O my reason for 1 star is you have to give it at least 1

I don't generally advocate having any alcohol when I drive but occasionally might use one of these kits after having had a glass of wine with lunch at a restaurant. Most importantly, these are compulsory to keep in the car in some EU countries, e.g. France.
