I liked it but sometimes it would read super high or super low. But overall I guess it did the job.

This is a cost effective device that enables one to be safe and avoid driving after drinking too much. While I don't know the accuracy of this device, I did try it out with a number of friends that drank alcohol during dinner. The result was that the people I who drank more did register a higher blood alcohol content as measured with this product.

This devices gives you a DECENT idea of your B.A.L. but is not really accurate. If you are just looking out of curiosity or for kicks it's fine. A lot of people who have DUIs and need a personal breathalyzer to make sure a car with Interlock ignition devices will start this is not a good option. If you need good accuracy spend the money on a higher quality device!
