Customer Ratings & Reviews

Fun "toy". I'm not sure of the accuracy, but it's fun at parties.

Gives you a BAC in the ballpark but certainly not precise.

This product works great, Definitely worth the money, No more wondering!

We have only owned this breathalyzer for just over three months, and it is already failing. The device kills a AAA battery in less than the course of a day. It also supposedly gave a false positive - the user swears they did not drink and a second breathalyzer (also from bactrac) read 0.00%, while this one read 0.014%. Will be contacting customer service as this is an expensive unit to fail so quickly.

I think it worked great! But like other reviews it did just randomly stop working unfortunately

Works very well and keeps everyone safe throughout the night!

Kinda expensive for what you get, it’s a little plastic keychain that is never accurate. It always gives a different result.

Recent purchase in the last week. Readings seem low and are also all over the place. Could be a bad device or a bad product in general. Woukd not recommend if you need accurate readings.

Definitely got super accurate get inconsistent reading based on how hard you blow

Not too accurate. And can tell u that u are beyond calculating ? Each beer is like .02. So 5 is .10. And it says max bac reached?

Useful on the go and in emergencies drive sober everybody

Have tried to get a reading over 20 times. Worked only once. Keeps giving error code of 'No blow detected'. Disappointed. Bought two. Both are going back.

I was really disappointed with this purchase. They seem easy to use but they are not. Multiple attempts are needed to get the device to register your BAC. I don’t recommend.

It works ok. Came apart pretty early and quickly. Would not recommend

Worthless! Only have had this for one month and it stopped working. I’ve got an alcoholic husband and I needed this to monitor his drinking. Sucks that it cost so much and lasted only a month.

Would blow 1.75 then next blow be sober. Not even close to accurate

Could not get it to work money down the drain !!!!!

Very inaccurate, after followinf all directions still inaccurate

I absolutely love my BACtrack keychain, It's smaller than expected, really easy to use and very fast. It seems incredibly accurate as well. Highly recommend.

This is the best thing ever. It's so small I carry it in my front pocket and don't even know it's there. It's nice to be able to read my BAC on my iPhone or right from the display. My friends and I love sitting out by the pool with wine and testing ourselves. Before testing with the breathalyzer it asks you to guess your BAC. We always guess too low! This isn't a nice to have, it's a must have!
