Hi,
This is a Chinese Servo. They seems decent enough for my application.
I don't think there is to much issue with these Chinese servos, they seem to operate as they should and while not top quality they are not
rubbish either, entirely suitable for our purposes.
Where I do take issue with these Chinese products is the Chinglish documentation and even more damningly NO PC based set-up and tuning software.
My advice to users new to servos would be to get a slightly more expensive but better brand like Delta or DMM which have vastly superior
documentation, support and set-up software. Once you learnt how to get the best from that thereafter you'll have no trouble transferring what
you have learnt to the cheaper brands, almost all AC servos are very similar to each other, if you can 'drive' one you can 'drive' others.
