Had it a couple weeks ago and it doesn't work. Not even close to accurate. reads way too low then if you take a sip of alcohol it raises the level about .1. Should have known such a cheap product would be useless
Bought this. It seems very in accurate. Drank half a beer ate some food and it reads .12 on average.. And that was waiting 15 min or so since last drink even.
This is a fun product, but very in accurate readings. Usually differs around .03 within 3mins of usage. Wouldn't use for the science but more as a party trick.
