I purchased this breathalyzer because I liked the size and price. I wanted to see what my ABL were in the morning the night after drinking. I seemed to work fine until I desided to “test” it and use it right after taking a drink. When the numbers read 0.00 I knew something was wrong. I think I will have to spend more money and get something more substantual.

I ORIGINALLY GOT THIS PRODUCT FOR MYSELF TO MAKE SURE I WAS SAFE. BUT I SOON REALIZED I COULD USE IT TO TEST MY TEENAGERS WHEN THEY COME HOME ON THE WEEKENDS IF I HAVE ANY DOUBTS ABOUT WHETHER OR NOT THEY HAVE BEEN DRINKING. THEY DON’T PARTICULARLY LIKE THE IDEA, BUT HAVE BECOME USED TO BLOWING IN THE BREATHKEY AND UNDERSTAND WHY. I SLEEP SO MUCH BETTER NOW!!!

I recently had a good friend get a DWI and felt it necessary to check my alcohol level when I went out; I have found the BreathKey an inexpensive way to accomplish this. I have been pleased to find that my alcohol level is lower than I would have expected in general

I have nothing to compare this to so I gave it 4 stars because it does work, but it seems expensive for such a little item that is about the same size as a car alarm remote. It is designed to be put on a keychain but there is no way in hell I would do that. Dirt can easily get inside the open holes and screw up the accuracy. This is too expensive for that.
It really should have a small carrying case. The one thing I don’t like about it is that you have to put your mouth on the top part of the outercase. There are no protective sleeves. I guess you are just supposed to lug this around in your pocket and then put it in your mouth when you are testing. Then you pass it around to your friends. Gross!
I got this device for personal reasons.
When I first go it, I blew a .000 since I had nothing to drink. Then I rinsed my mouth with Scope, and blew a .200. That is about 2.5 times the legal limit. After about 10 minutes or so it did go down to .000, so I know it works at least.

I’m a heavy drinker. I bought this unit based on it’s reviews for it’s accuracy. I’m disappointed. Granted all (I’ve done my research) commercial Breathalyzers I’ve researched seem to have their quirks- take a deep breath then blow slowly, don’t inhale then blow normally, etc. I don’t even know at this point if police breathalyzers can be considered legal, because they all, at least the commercial ones, seem to come down to these rules- you can’t consume any alcohol, food, drink or cigarettes within 20 minutes of the test. Now, as I’ve said, I’m a heavy drinker, and I’m 43 years old, but I’ve never had a DUI, or any alchol related encounter with the police… but based on this weird 20 minute rule, I’m going to assume that the police can’t even give you a breathalyzer test until 20 minutes after they’ve stopped you… does anyone know if this is what they do?
