“The mouthpiece itself is fine...it's a small piece of plastic. However - I ran some tests after having 3 beers one night and used the mouthpiece vs. blowing directly into the device. I found a big difference. By using the mouthpiece, my BAC was consistently .02 less. That's the difference between a DUI and not a DUI. So don't use these - blow directly into the device!!!”
“This product offers great value for the money. I love the bluetooth interface with my iPhone. I like how it gives specific instructions and gives an accurate reading with the ability to store data. Great product overall. Anyone who drinks should have one of these along with an Uber account!”
