This thing is a must if you EVER consume alcohol away from home. Not just for you (although that's certainly a good enough reason) but ALSO for your friends who may be consuming adult beverages as well If it keeps you or someone you like (say much less love) from operating when impaired it's paid for itself dozens of times over, never mind the risk of something really horrible happening that money can't fix.”
“Haven't used it that much as we don't drink that much, but it's great to be able to compare what I think my bac is and what it actually is. If I'm even close then I won't drive. Gives us peace of mind knowing we don't put anybody's life in danger.”
“No idea where to get it calibrated but have had now over 350 blows into it to make sure I'm fine to drive. May just purchase another after all the service this one has given me.”
