The Keychain Breathalyzer is a practical gadget for drivers. It offers an extremely affordable way to own the ability to test your blood alcohol content at any time.
Just blow into the breathalyzer, and in less than 5 seconds, its LED indicator will become green for “good to go,” yellow for “stop drinking,” or red for “how in the world are you still standing?” It can also double as a keychain, so you’d always have a handy solution nearby.
It even comes with an orange LED flashlight!
At a price tag of $5.99, you just have no reasons to resist this useful breathalyzer.
