    Involvement:Expert (understands the inner workings) - Ownership:more than 1 month

    Pros:

    - It's cheap but looks solid.
    - Works as expected.
    - So far quiet (without annoying buzzing).
    - Screw terminals for wires.

    Cons:

    Does not have the heat sink although it might not be necessary to have one
    Haven't notice any real cons yet.

    OtherThoughts:

    The adjustment pots are not described on the PCB so little guessing is needed.
    The coil is not fixed to the board - would be nice to glue it to the PCB.
    There is no input polarity protection diode so do not swap power cables!
    Overall quite useful piece of product.

    Bottomline:

    Definitively worth the money, so buy it if you need one.
