Customer Ratings & Reviews

I bought this just to see what my BAC would be when drinking but it's become so much more! Not only does it tell me my BAC but it also tells me the estimated time of when I'll register a 0.00. It's been reliable so far so I'll keep using it! Love this unit and it comes with a case.

Prevent Dui costs Tells u when sober Great app My friends love it We always see who is drunker

As a former Police Officer, I was skeptical of this item's ability to accurately predict BAC. The item says you should go 15 minutes without a drink before utilizing it. This is absolutely true; attempting to use it before this time will result in a much higher reading! Overall it seems very accurate, but if you blow too hard the result is higher, if you blow to softly the result is lower. Eventually you get the hang of it and can get a good idea of whether or not you're legal to drive!

Bought this for my 21 year old son. Making him aware of how much he drinks and ensuring he does not drive under the influence. It keeps him mindful of being responsible. It works great. He Has let his friends use it to keep them off the road too when drinking. Works great and saves lives.

I love this thing, keeps me out of so much trouble. I always check to make sure i'm good before i do things. The device has shown me that even when i think i am, i'm really not. You can never be too safe! the charge lasts a while, and it always allows other options if your too impaired.

Bought this for my son to keep in his truck when he is out having fun with his buds. Now they use it to make sure that they are all safe to drive. Everyone wants to know where it is at the end of the evening.

Saved me from a dui, because I chose not to drink after seeing I was over the limit. It's a great party trick

Previously bought a cheap one that was not accurate and only allowed 1 breath every 15 minutes. worthless. This is reasonably accurate and tracks to an ap which I can better predict my future BAC by monitoring a graph during and after drinking. Bit pricey though.

Works very well. Compact design. Good price. Something to keep in you car.

Works great. Needs a note easy to find to make sure you have not drank, chewed, or smoked within the last 5 minutes though. Moisture does ruin the device. Has kept a few out of jail. Would recommend for anyone who drinks and drives.

This BAC monitor is OK... now that I have it I do wish it had a screen on the device. Instead you have to open your app to see results.

Just dont bother going to the Bryant Irvin store in Fort Worth for anything ever. Once you locate another store the sales service and product orientation for this is great. Tested product multiple times and it appears to be very consistant and reliable.

A life saver. Cant stress enough when your out having a great time.

Would prefer if it had a readout on the device and didn't require phone Has the better quality sensor, would be curious to know how similar/different results are

I prefer to take Uber when going out with the guys but this is good to have to check after you've had dinner out and a couple drinks.

Excellent product super accurate good buy definitely recommend

I take a sample whenever I'm about to drive and compared the results with my friend's breathalyzer (he's a cop) a few times, and the results are the same so I'm very confident of this product reliability.

Very useful when out drinking and finding out if you're close to the limit. Remember no eating or drinking 15 minutes prior to testing for best results.

It helps to know how much is to much before i can drive.

Doesn’t give you much for directions on how it’s used when you’re in the app but reads to the hundredth of a percent accurately
