Includes 2 reviews aggregated from around the web.
There are few reviews for this servo on the web. A retailer shows 2 reviews, both 5 stars. One buyer calls it a great replacement for Freewing 17g servos with much better speed, resolution and torque, though not quite as good as an MKS HV69 and at a lower price. The other found the control arms a little tight to install.
