A lot of fun to pull out at the bar. Takes some practice to use it correctly, but it works and the price is right.

I purchased this for my boyfriend who really didn't understand that it doesn't take much to be considered legally drunk. It has been a real eye opener for him.

It seemed accurate enough. Although it does not work if someone binge drinks a heavy amount of alcohol. I don't know what the max is.

I purchased this to make sure my friends were not making bad decisions. Unfortunately I found it to me less than accurate. It could be fun as a party favor.
