AT178 LCD Digital Alcohol Tester Breathalyzer (0.19% BAC Max)

Pros: Works just like its supposed to work. My friend gargled Listerine for half of a minute and tried it out and it worked perfectly fine. He later tried it out with real, drinkable alcohol and it worked for that too. its fun to use to see how drunk you "legally" are. you can also use it right before you drive to see if it is safe and legal to drive so you won't get busted by the cops if you get pulled over!!! it is funny to see how much different types of alcohol affect your blood alcohol content.

Cons: You have to let it warm-up for like 18 seconds before you can blow ionto it so turn it on before hand or you will be waiting a short while for it to fully turn on.

Other: if you want it get it! if you need it get it! it is more than good, its GREAT!!! so get it!

Pros: I tried it just after recieving it. It showed 0 as expected. Then I tried it while drinking with some friends, it showed some reading that could probably have been correct.

Cons: After that it apperantly broke and started showing 0 for everyone even though people had been drinking. I couldn't get it to work again.

Other: It's cheap but the quality is bad, get another model. Using this to see if you're fit for driving is probably dangerous.

Pros: Works, but only with your nose not blowing. 1l beer on me gives a .4 measurement (it could be correct) and looks linear.

Cons: if you left the bateries on it consume them all even if you dont use the device the measure is not very repetitive (each measurement could change betweens measurements and time between them) If you saturate the sensor it will not work for a while

Other: It is fun to use with friends but not for test before drive I recomend it for fun. But remember to remove the batteries after use
