A typical keychain mini-breathalizer with stop watch and LED light.
You’re not going to find many breathalyzers smaller or less expensive than the GTMax. However, you will find breathalyzers with more detailed features if you are willing to pay more. This item is a great example of the keychain mini-breathalyzer.
The Keychain Alcohol Tester is 80 mm long and retails for only $10.99. Rather than using numbers that indicate the amount of alcohol in the blood system this device uses traffic lights to indicate the blood alcohol content. A green light indicates a blood alcohol level below .02, a yellow light means the alcohol content is between .02 and .05 and you should wait to drive, and a red light means that the user is has a blood alcohol content above .05 and that person should not drive.
The GTMax has a range of .00 and .19, has a test accuracy of .01, and uses two AAA batteries. The device also features a stop watch and LED flashlight.
It is important to note that police have warned against using such simple breathalyzers, though this item does make a novel gift for a friend.
There are several vendors on Amazon where you can purchase the GTMax mini keychain breathalyzer.

I’m going to get one of these mini-breathalyzers for a friend of mine who just got his second DWI. He’ll think it’s hilarious. But seriously, don’t drink and drive.
Thanks for the comment. Mini-breathalisers do make great gifts.
