    Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month

    Pros:

    These 7-segment displays are very useful, very small and with a very good brightness. Leds inside use a common cathode, so you only have to use one resistor to connect the display to your board.

    Cons:

    If you are not an expertise and works with Arduino, there is no library to work with it, so you need to manage all the led by yourself.

    OtherThoughts:

    In my case, I have implemented a simple library to work with this 7-segment display. You can select if it use common cathode or anode and, after that you select the 8 pins of the display. So, finally, I work with this display as an LCD, sendind command like "print" and so on.
    With this library, I very simple to use.

    Bottomline:

    Summarizing, it works very well and it is a very cheap product.
