RE: anyone use this servo?
IMHO dismissing things you haven't tried outright and proclaiming that train of thought to others, is a form of fear mongering.
... Not to single anyone out at all .... but this happens quite a bit around here, and often leads to all sorts of rumors, that are often repeated over and over... hence the "the less expensive servos don't center as well" types of posts.
You don't have to be the first to try something new.... some of us do like to try new things however... that leads to some misses, and some real finds, no matter the doubts.
