Go Keychain Breathalyzer, Portable Keyring Breath Alcohol Tester

If you like your drink like I do, this little device is an absolute life saver. After you stop drinking, it helps measure when you are fit to drive again. Tip: Eat before you drink and drink plenty of water after you stop. Helps accelerate sobering up.

This is surprisingly accurate. Only bought for peace of mind if have 1 drink of beer or similar. Or used to for fun with friends to see their alcohol content .. (for fun they are not driving!) Great quality and accuracy for the price

L'idée est bonne mais même en respectant les délais entre les utilisation les résultat sont complétement aberrant vous pouvez passer de 0.11 à 0.8 tout en buvant votre bière et je n'ai jamais réussis à dépasser les 0.13 même en me rinçant la bouche au wisky avant de souffler (c'est dire) mais il est joli

At the beginning I used it and the results were confusing. But soon it was better…

Non è molto preciso, usato dopo aver bevuto da risultati bassi. Utile per avere un’indicazione generica

Me gusto
