it's precise, at least i used it one night and it said i wasn't drunk, then a policeman stopped me to check my BEC and gave a ngative.
it's easy to use, just blow
a great source of ethanol semiconductor sensors for hobbyists
It can be perfectly used in Spain, cause it't calibrated fot the actual limits here
a bit hard to understand the instructions
it sometimes doesn't want to measure and you have to reset it
a bit big to be a keychain
better if it could be calibrated
it's a good indicator of your BAC to check if you can drive or not
Also good to check if your friends are drunk or not. It's a cheap useful product
hard to find a cheaper solution to check your BAC, i think that almost every drinking person should have one of these.
