I was unaware that it was even possible to own an at home breathalyzer test until I noticed one at a friends house, I thought this was a little odd at first but than realized how great of an item this would be to have on hand.

This is great for those of us who like to entertain guests at home, whether its summer BBQs, family dinners and even holiday get togethers, it would be very comforting to be 100% sure of someone's ability to drive, especially as the party host.

This was very easy to use it needs 3 AAA batteries (not included) and it also comes with 5 extra mouthpieces with 1 already on the machine. From the first time using this it was clear to see that this gives a reading even with a small amount of alcohol which is very reassuring. I would defiantly recommend this! I ordered this from Amazon.ca and it cost $23.99.
