3.0 out of 5 stars not accurate March 31, 2012

By Bob

Color Name:Polished black|Amazon Verified Purchase

This thing is quite a battery hog (AAA size). Had an alocohol sensor unit that cost more and seemed to be more accurate than this one for a decade before it quit working. This one registered a 0.01 after a beer a few nights back- seems to work so far. Don't drink that much nowadays but I want to know just where I stand... One can get into serious trouble if he hurts/kills someone while driving impaired.

Will update this after I compare it to the BACtrack S80 fuel cell model that I recently ordered arrives.

Update: Drank two beers 24 oz. total. Here are the results as my body eliminated the alcohol. Three digit numbers on the left are the pricy fuel cell model results.

6:56pm .029 vs. .06 BAC
7:12pm .022 vs. .04
7:21pm .020 vs. .03
7:38pm .016 vs. .03
8:36pm .000 vs. .00

The two digit numbers on the right are this inexpensive keychain model. The three digit numbers on the left are the BACtrack S80 $136. model. My stomach was completely empty when I did the above comparison. My old alcohol sensor unit seemed to be more accurate than this one. A fuel cell model is the way to go if you really need accuracy and not a vague idea...

Blew into a fuel cell looking model years back when a cop thought I was drunk. He was puzzled for I was well below 0.08 but had alocohol on my breath... Am glad I have an accurate fuel cell breathlizer now. Cheap insurance considering the potential ramifications of being over 0.08% BAC. Figure on the high probability of a blood test for any and all drugs if you look/smell/act impaired. The courts have upheld the use of blood tests at the discretion of the cops.

1.0 out of 5 stars Not accurate April 3, 2012

I blew .00 with this product but blew .016 with a breathalyzer at a police station. If you need accuracy get a breathalyzer that uses fuel cell technology to detect alcohol. It's what the police departments use. No sense in using this if you want to know if your under the legal limit or if you shouldn't be drinking and need to blow for probation.

5.0 out of 5 stars This is a great little breathalyzer that actually works! November 22, 2011

This is a great little breathalyzer that actually works! Finally a company has produced a keychain breathalyzer that is accurate and easy to use. I have tried some keychain units in the past and there were useless. This one will actually display the digits for your readout instead of some flashing lights. It's also small to keep in your pocket if you don't want everyone seeing a breathalyzer on your keyring. Will be getting more for some holiday gifts for friends.
