Customer Ratings & Reviews

This is our second unit as the first broke about 6 months after purchase. The back had to be taped shut within 3 weeks of purchases. While its overall use is to effectively determine if someone is legally drunk it has become a part of many adult weekend drinking parties.

we have had a lot of fun with this at a party and it is also useful

If you consume alcohol and have to drive, this product will help you know if you are over the legal limit. Also great to test someone to see if they have consumed any alcohol. Has been a great product for me.

bought this before going to Vegas for a week tested myself every time i had a few and i think it was pretty accurate good to know this technology has been made available to the average consumer

Great inexpensive option to be sure you are safe to drive,

Product appears to work well. Seems to be very accurate.

Okay, just using it as a quick check for , "Should I be driving?" Not a guarantee, but a pretty good indicator. When I carry it, I drink less...so I guess it works better than imagined.

I find this to be an average product. Again you are buying a keychain unit so for that its perfect. The on button is a bit sensitive but other than that, it works and gives you a heads up on your BAC so if you are in question its a great informative piece, use good judgement

It works well. I bought it for my fiancé and he loves it!

Wanted something handy to test and this one meets my need.

I bought this as a gift at a get together. It was fun to see how drunk we were. I believe it worked well however we were new to it & barely read the instructions & drinking at the time. We did have fun though.

We purchased this as a gag gift for my brother. He loved it, used it at several Holiday Parties, which was a terrific ice breaker. We all checked it out, and the breathalyzer gave us an accurate rate, saying we were safe to drive home.

Bought this as something to do with friends while playing games and having a few drinks. I don't know if I would use it as a way to tell if someone is able to drive legaly. The results seemed to varry though. So that's why I wouldn't recommend using it for legal reasons. Purchased extra tips, so all my friends could try it. Had a lot of fun.

As far as I can tell, this works great. I have no way to verify. I am not a big drinker, but it is nice to know I have this available should I or any of my friends ever decide to have a few drinks.

love this! This is the second one we have bought due to losing our first one but we love it and everyone always wants to try it. Also, verified its accuracy by a police breathalyzer. All our friends want one!

Easy to read, easy to use. Just use it as a key chain.

It works fine I haven't had any problems with it so far

Okay product is good had good experience with best buy

It was so good had was going to grab another one for my holiday work party

Not sure how accurate but works well. Would recommend
