Reviews (3)
Includes 3 reviews aggregated from around the web.
There are few reviews for this servo on the web. Buyers who reviewed it at one robotics retailer call it a reliable, strong servo, one having used it in several builds where it fits nicely between full metal-gear servos and cheaper standard servos, and others call it a good product and fill a gap for robot builds. One buyer found it too big for the space and one had not used it yet. A hobbyist also reported that the elbow servo in a robot arm kit stopped working properly after a year, though it was unclear whether the servo itself or the setup was at fault.
