what our customers say

My boss bought the entire office floor these amazing and handy devices. Many DUIs happen the next morning... we are so fortunate to not have to risk our jobs, family and more by having this in our pocket! My husband is a police officer, and this was the same accuracy as his field sobriety kit! It should be mandatory to have these in your glovebox...


Speedy delivery and well packaged. It's very easy to use and comes with ten disposable mouthpieces, clear instructions and a big green display on the readout screen. Takes out the guess work, it's an excellent product.

-Mr A R Chapman

Very easy to work and understand the readings. After dealing with a tough family life this really helps to maintain the situation with an alcoholic.
