“I was skeptical, but got one to test it out and see if i could rely on it for those early morning car journeys where you err on the side of caution and take a cab, as you perhaps had too much the night before. Works really well. Certainly provides a degree of confidence on a few mornings I've used it to see what it says when I know I've not had much to drink, or had a skinful. Is it scientifically accurate? I can't say - but I use it now to tell if I did have that last drink at 10pm or 2pm. I can be sure.”
