“First, you should know the device comes with 3 mouthpieces (I unnecessarily ordered the 10 mouthpiece pack.) Second, this is a handy device to have when you know that you'll be drinking and driving. It fits nicely in a pant pocket. I like the look of the device and have had no issues since owning it. I recommend this device.”
“I got caught, and it would have been easily avoided if I had known I was over the limit. By using this you can gauge where you are and make sure you stay within your limits. I would never suggest you drink and drive but if you do... know where you stand before you try it.”
