    Pros:

    - The display is easy to understand.

    - Includes wrist strap.

    - Cheap!

    - Includes manual.

    Cons:

    - No batteries included.

    - When blowed too close, the dispay get "blur" and hard to read.

    - Maximum BAC is 1.9%. Can't go even further.

    - If you just drink, wait some seconds before blow, because there is alcohol in your mouth.

    OtherThoughts:

    - Instructions:

    1. Press the ON button until turn on (bip emits).

    2. Wait for 10 seconds for warm-up (bip emits).

    3. Blow air from your lunges, slow, the maximum time you can resist.

    4. Check the results! If you are drunk, many bips emit!!

    Bottomline:

    - Because of the price, its worth to buy.

    - I got three of those!
