Breathalyzer Keychain +Flashlight + Stopwatch…What More Do You Need?

New mini-Breathalyzer right on your keychain. Never again have a doubt
about how much you have had to drink or whether you are legally OK to
drive. This mini breathalyzer has a traffic light readout system
making it super easy use. Simply blow for 5 seconds then wait.
Indicating green and you are good to go; yellow and you may want to
wait a while before you go home. If it indicates red then you should
hand your keys to friend. This is great reference tool for seeing if
you have had just a little too much to drink, but be careful to not
rely on this as an iron clad test!
