  • Cheap & Small

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

    Pros:

    Yes, it is a servo, and it is exactly like advertised: Strong, Small, Cheap, Lightweight. Only 9 gramms.
    It does not, in my case, travel all the 180, and didn't return all the times in middle position. As I only have one I cannot compare.

    Cons:

    Screws to connect the arms are not easy to insert, but it also can be a pro; as the arms are a tight fit.
    The gears, like others also mentioned, are plastic. I wonder how long it takes before malfunction.
    No documentation.

    OtherThoughts:

    Price can be lower for such quality, eventuaally the gears will probably be the weakest part.

    Bottomline:

    If you need a rather cheap straightforward lightweight servo, this one can be yours you need.
