The 6 Best Keychain Breathalyzers
We spent 25 hours on research, videography, and editing, to review the top selections for this wiki. Driving under the influence of any intoxicant is never a good idea. While the compact keychain breathalyzers on this list should definitely not be relied upon to guarantee you are sober enough to get behind the wheel, they can provide an indication that it's probably wise to open up that app and order an Uber or Lyft to get home. When users buy our independently chosen editorial picks, we may earn commissions to support our work. Skip to the best keychain breathalyzer on Amazon.
