I use this way more than I would like to admit. Life Saver!!
Great to have around. Works very well.
If you drink you need this product ... a real eye opener
Absolutely love it. Great for both recreational use and for determining whether I can let people drive from my house after drinking! This has saved some friends (and myself) from potential trouble
What a good idea to have a personal breathalyzer to keep in the car. Works like a champ.
Everyone needs to have one of these around. They easily fit in any pocket so you can even bring it around with you. For what it can save you in costs later its an absolute bargain.
-Parties and making sure everyone is safe to drive
-If you are drinking at home and think "I am fine to just drive down the street for groceries" but you dont really know that
-Going out when you know will you will be drinking
-Having fun with people letting them use it
