    This helped me realize how much, and how long, alcohol effects me. It's easy to use.

    Easy to use. Lightweight and simple to take with you. Good quality with low cost. Only improvement I would request is having the errors codes annotated on the device would be helpful. I had to look up BACtrack's FAQ on their website. Otherwise, I like it and would recommend it for fun or responsible decision making. Note: Error was FL which meant not enough blow pressure. User error. Haven't recieved any other one.
