My mom passed these out to my sisters and me at a family gathering earlier this year and we thought it was funny but it has honestly been the best gift ever! I use it all the time when I am out and if it says I am close to or over the legal limit then I call a cab and don't worry about if I *think* I am ok to drive and hope I don't get pulled over. Such a thoughtful and useful gift for someone you love. I just got one for my husband as well as the additional mouthpieces because our friends ALWAYS want to use it to to test themselves before they get in the car. I absolutely love this and highly recommend!
Bought it earlier this month. Don't really know how accurate it is, but if it is even close it's educated me on how little it takes to be legally drunk.
Step 4 of the operations says that it will let you know when to breath with a beep and a red dot. Mine doesn't. Then it says to blow for 5 seconds until it beeps and guess what? Mine doesn't. I think it is a great product but I just want to know if anyone else had the same problem?
I bought this about 3 months ago, I've given it some use now. it appears to work as described, however I'm still unclear how accurate it actually is. at my body weight a certain drink count over a set number of hours should be a consistent reading but I'm getting various readings much higher than BAC charts indicate for that amount of alcohol would register. It's a useful tool to keep me thinking about my consumption levels over time.
Bought mine a month or two ago. Not only is it nice to know where we stand when we're out, but it's a lot of fun when at home! A great source of conversation and piece of mind for a very nominal purchase price. Worth twice what they charge. Get yourself one. You'll be happy you did!
