Handy and works great!
I bought this product because I wanted a breathalyzer and it works wonderfully! I keep it in my glove compartment and have used it already on several occasions. It works great just to see how much alcohol affects each person and it is quite fun to play around with at parties. The instructions are detailed in the manual and simple to use and understand. I am thinking about getting another one for my other car just so I don't have to move it around. Overall fantastic product!
