“I ordered the keychain version, the shipping was fast but unfortunately that's the only good part. My device stopped working after only 2 weeks of having it and when it was working the readings were very inconsistent. Blew a .00 after four shots. Don't waste your money.”
“Not sure if mine is defective but tested out with my husband. We had two drinks and waited to test. We tested and then retested 20 minutes later. One went up with no drinks and the other went down. Also if you test within 5 minutes you get very different readings.”
