Rated 5 out of 5 by from Great Product! Bought the Vio smartphone analyzer last month, and it works great! The breathalyzer is compact and easy to use, and the smartphone integration is flawless!

Rated 2 out of 5 by from Backtrack Vio I bought this product to test my BAC after social drinking, but it often turns itself off just before warm up, unable to get a reading half of the time. Don't know if this is a bug with the app, or a problem with the unit itself. Can't recommend it at this point.

Rated 1 out of 5 by from Bad Product I bought this product about month ago. At first it worked, but only sporadically. It gave frequent error messages, and usually required several tries before rendering a result. At first I thought it was the batteries, or that it went through them quickly. Now, even with new batteries, the device almost never gives a clean reading. It's worthless, and I should get my money back!

Rated 1 out of 5 by from Inconsistent 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.

Rated 5 out of 5 by from Brilliantly Simple Device 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*
