Customer Ratings & Reviews

Works well for taking high scores at parties, would not trust it for actually determining if your safe to drive. Seems pretty accurate though.

Works great, has helped me with recovery and regaining the trust of my partner by being able to show her my BAC at any given time. Only improvement would be a date and time on the display.

Took it with me to a party and before anyone could leave we had them use it. Everyone pasted!

This helped me realize how much, and how long, alcohol effects me. It's easy to use.

I've had to blow a couple of times to get a believable result. So I would definitely not trust it to be Law Enforcement Accurate. It is an entertaining conversation piece.

Bought breathalyzer because I had a few DUIS when I was younger but still like to enjoy a beer now and then I have the option of checking my alcohol level at anytime

Product is accurate but the quality is poor and cheap. Sensor when out within a month of usage. Best only has a 15 return and they refused to replace it. Call the manufacturer and they required a ton of information and time to even receive a replacement. Very dissatisfied in my purchase.

This small and simple to use BAC keychain has been a real crowd pleaser thus far. Works like a charm and it is simple to use. So far it seems pretty accurate, just takes a good amount of blowing to get a reading. It has definitely helped to ensure nobody left the house over the limit when drinking.

Product review: Efficient. It comes with 4 mouth pieces for when you have to test your friends. I wash them in the top rack of the dishwasher and soak them in disinfectant. While the breathalyzer will give you and immediate estimate of your drunkness, you have to wait 20 minutes after eating or drinking anything for a perfectly accurate number. It's fine, you just have to have a 20 minute wind down from the party. I think that everyone who drinks or cares about their friends who drink, should have one on their keychain. Only one downside: remember how the back battery cover of your gameboy somehow always got lost and then one day you stopped caring because "hey, it still works"? Yeah, same thing. I lost the battery cover about a week after I bought it. I put one those little clear rubber bands around it, so my battery wouldn't fall out when every I dropped my keys. My experience: My friends like to have a party every couple of weeks and sometimes it gets a little.... out of control. Not only is this great party fun (pass the breathalyzer), but it has most definitely helped me save a life or two. Everyone party has that one person who swears "No IIII"mmm fiiiiiiiine. I can TOTALLY drive. It's cool," and everyone cringes with fear at the thought, but no matter what anyone says, they just keep trying to leave. It's become a ritual that at the end of the party, everyone gets the test before they leave. Those not at 0.00 get to stay until they are or spend the night on the couch. I won't have anyone endangering themselves or anyone else by drinking and driving. It's interesting though, I wasn't that popular or cool and I guess I'm still not the socialite everyone wishes I were, but because I got this breathalyzer, and forced it on everyone, I am more respected and I definitely get invited to more parties.

Easy to use. Lightweight and simple to take with you. Good quality with low cost. Only improvement I would request is having the errors codes annotated on the device would be helpful. I had to look up BACtrack's FAQ on their website. Otherwise, I like it and would recommend it for fun or responsible decision making. Note: Error was FL which meant not enough blow pressure. User error. Haven't recieved any other one.

Chug a beer then hit this bad boy to make sure im under .12 (legal limit)

Product is not the best one you can buy, but for $40 it is well worth it. It has been proven to be helpful and very accurate. Product can fit on a keychain making it convenient.

Bought this just for fun/curiosity. Sometimes the numbers are inconsistent when multiple readings are done in a row. However, it’s a good deal for the price and in general provides a reasonable reading range. I would be hesitant to recommend if you are actually planning to use this to determine driving sobriety.

The BACTrack has given me extra peace of mind to know that I or friends won't try the "I think I'm just fine to drive home" tactic. This device is small and can easily be added to a key ring or put into a pocket. $30 is a small and easy price to pay knowing that yourself, family, and friends are safe and legal to drive after drinking alcohol. It also helps keep the ones, you know who have had too much to drink, from getting behind the wheel of a vehicle. It's better to blow into your own breathalyzer than into a police officer's breathalyzer. As the packaging states, wait 20 minutes after food or drink before blowing into the tester. It will give a much higher reading (about .02+) if you blow right after having an alcoholic drink. As with all drinking, be responsible.

I bought this as kind of a joke. I didn't expect it to be 100% accurate but it really is close. I have friends who are police officers and they claim its about right. It will also let me know if I'm safe to drive home after a couple of beers. Its small and light weight with a loop for your keychain. Over all its just fun.

This unit is small and effective. I keep it in my purse, but is small enough and equipped to be put on a keychain. It is a decent gauge to help a person make smart decisions :-)

As long as you read the directions , and follow them , this device works great ! You must remember to wait 15 minutes after your last drink to test for a true reading, and I put the BACtrack to the test at my home, and writing down the results after having (3)16oz. Coors light. If your eating also , you must wait 15 minutes also before you do the test. The BACtrack Test that I performed at home were very Accurate and, it's very durable and easy to carry in your pocket. For the price of BACtrack it is worth it and, saves you from putting others in harms way.

I got one just to have one. Out of the box, it worked fine: one drink registered correctly, and three drinks in, I believe the reading was plausible. Over time though, the gadget became less accurate, erring on the high side AND reading "high" for longer than realistic. This was confirmed with a friend's (better) unit. Obviously, calibration was an issue, and that's not something one can do in-house or local.

I bought this product in the car section while looking at stereos i thought it was a good item to add to a key chain since its so small and easy to use. Fit in my pocket without notice. Would def reccommend this item for anyone who goes out and drives dont take the chance

Do the job. Always use it before driving. Recommend to follow the instructions before the test. So you will get the right reading. 4 stars for battery came inside is expired.
