“I have one of these. I use it when my friends really shouldn't be driving to convince them to take a cab. I also use it when I'm trying to see how drunk I can get. I also bought one for my Uncle because he loves gadgets and bourbon.”
“I bought this for my husband for Christmas and we love it! It's extremely accurate, we even tested it along with a data master (the one the cops use) and the results were the same. It's so easy to use and syncs right up to our phone. It's a hit at parties and really gives you a great idea of how much liquor you can handle and how long it takes you to process it.”
“I've had mine for a couple of months, and have been pretty impressed. It's easy and fast to pair, and is small enough that it's pretty easy to stash in a pocket or car cupholder. I've used portable breathalyzer a a few times over the years, and this one seems to be the most consistent. Would be nice if it had a small display on it to show BAC so a phone wasn't mandatory for use, but that's a minor gripe. I would recommend it.”
