Not a perfect product, but fun to have and never a bad idea to bring along to a party.
It isn't the most accurate breathalyzer on the market, but it can give you a general estimate of your BAC. Plus, it's a fun thing to have with you at a party (not to mention probably a responsible one), and it's very small. It's really the perfect size for a keychain because it doesn't add much extra bulk. In fact, it's only roughly the size of my car key fob. I added a comparison photo to demonstrate. I'd recommend this item seriously to anyone who has a general understanding of how BAC is calculated and about the time it takes for alcohol to metabolize in their system.If you understand how these things work to some degree, then it's a handy device to have on your keychain if you're worried that you may be just over the legal limit (0.08 in America) to drive, or if you want to check and make sure that you're pacing yourself appropriately during a family function. However, it is not a high-enough-grade tool to base serious decisions on its estimated numbers. Many factors can affect the number displayed by the device and it likely won't often hold up to the precision of an official, police-administered breathalyzer test.So yes, it's a very cute and inexpensive product and it makes for an excellent gift. I use mine every now and then just out of curiosity or to double check when I'm already fairly certain that I'm in the clear to drive home. My friends get a kick out of it too, often insisting that everyone blow just to see who scores the highest. It's inexpensive, it's cute, it's handy, and though such an item can easily be joked about and played around with, it also has the potential and purpose to prevent people from making serious mistakes.
