I am pleased with the performance of this product. It's simple, it works well, and the price tag is nothing compared to if the cops get you.
I reuse mouthpieces and haven't had any problems - definitely no need to throw out a mouthpiece after a test.
The screen is bright and easy to read. That's a plus.
Results are consistent test to test. If I blow 2-3 times in a row I get similar results. This was not the case with a previous breathalyzer I had purchased. Definitely worth the money to get this type of higher end unit.
