alcohol level is after a few drinks. You feel fine,
but are you over the legal limit? BreathKey
was developed to help you measure your
blood alcohol level and protect you and others
from severe consequences.

states BreathKey, with its keychain design, is
the smallest, lightest, and most reliable digital
breathalyzer on the market today for the price
when compared with other breathalyzers.
