“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.”
“After drinking all night, it never registered higher than a .07. After my first beer - .07 after my fifth beer, same thing .07. I know for a fact I could not still be at a .07 afeter 3+ hours of drinking. I took repeated tests and would sometimes register .06. I just received this today, and already it is inaccurate.”
