Great gadget if you plan on driving after having a drink or 2 or 3. It gives a pretty accurate read as long as you follow the instructions and don't abuse it.
Everyone should have one and if you have had a drink...do not drive. Share your Breathalyzer with friends by carrying mouth tips....my friends were blown away when they saw their results. Give Breathlyzers as gifts...especially for graduation. We will never know how many lives we save by doing just that....but know that you made a difference.
This is my 7th Bactrack breathalyzer. I purchased 6 of the key chain and used as gifts. This is an excellent product to help keep myself & my friends staying safe.
I tested it using the body-weight-drink-volume charts, and the BACtrac gave textbook results. I used it at a fish and game club event so no one would go home intoxicated. It worked very nicely.
I bought 3 and gave them to friends that I work with , since I work am a bartender. I already had one and it is a great tool for people that think they are ok to drive. NOT!They are easy and work great.
