BACtrack Vio Reviews

3.7 Rating 94 Reviews
Within the first six months (because it needs re-calibration every 6-12 months), I noticed inconsistency when taking a reading. I would have to take 3-9 samples back to back to see if there was any pattern. What did I find? No pattern. It would go from 1.0 down to 0.03, up to .09, down to 0.07, then down to 0.03 again, then up to 0.05... it was always inconsistent with no pattern. I would understand if it consistently got lower or higher, but this thing couldn't be read. I better be able to send it in for recalibration without postage charge because this company is not commercializing a reliable product.

I received this product over the weekend. I tried it after a power nap after I went to brunch and had a BAC of .048, which seemed believable. 6 hours later, without having any more alcohol to drink, I tried again and had a BAC of .024, which isn't very likely. I tried again the next morning, again without having any more alcohol, and the BAC reading was still .024. I also have a device in my car, which will not allow me to start my car if I am over a .02. This device was calibrated two days before, and I was able to start my car immediately after receiving the reading of .024 on the Vio. I am not impressed.

Totally unreliable. It reads 0.000 even 20 minutes after having several drinks at home. Occasionally it will give an accurate reading...but only about once or twice in about 10 tries.

Brand new just bought this so I drank seven shots to test waited 45 min and it worked but blew a .00 several times so I question its accuracy

I bought this device quite awhile ago and I have noticed it is not something you buy for accuracy. If you do not blow into in the exact perfect way, you will get a 00.00 reading. Even when I can get a reading, I never get the same results back to back. Still good for ballpark estimates and great add on to my car keys

I'm very impressed with the little keychain Vio breathalyzer I purchased. It has earned me the name "Mr. Responsible" and that in itself is remarkable. Thank you for providing such a simple device to use. And making it a keychain was a stroke of BRILLIANCE! Not only do I enjoy the hardware (the Vio itself) but; the software you provide with the application (app) is very informative and helpful. Thanks again for providing such a wonderfully simple and brilliant piece of technology that helps make for better choices. *HIGH FIVE*
