Discreet and accurate-good to have on hand

Great to have in the house/car with new drivers in and out! Easy to use and it comes with several mouth pieces to keep it clean for each user.

Don't depend on this item! It will not help you be accountable.

I purchased this item to hold someone accountable. It only worked once, the next time we tried to use it for him to prove to me that he was not drinking.... error messages.. was all that came up. This was a huge waste of money and the return window had already passed. Very dissappointed in this product for such an important issue.
