The Keyring Alcohol Breath Tester is a 3 step test that's a must have item when you're out on the town.

Straightforward to use, simply hold down the power button until the LED turns green and blow across the top of the grill.

If the light remains green, you're under 0.05% BAC*, and should be in the clear. If the LED turns yellow, then you're on the borderline of being over the limit and should think about using an alternative way to get home. A red light is when you really need to find a bus/taxi/sober friend, as you have exceeded the 0.08% BAC.

Although this device should only be treated as a guideline, it will help you prevent making any more bad decisions as to whether you are really fit to get behind the wheel. - L.M.

Be safe, this Keyring Alcohol Breath Tester is excellent. I am a delivery driver on flexible time and I couldn't do without it.

Cool device, seems to work, need 2 AAA

I would recommend this Keyring Alcohol Breath Tester. It's easy to figure out and useful, the only thing is that it needs 2 AAA batteries which don't come included.
