Reviews (2)
Includes 2 reviews aggregated from around the web.
There are very few reviews for this servo on the web. Two buyers rated it a perfect 5 out of 5 at one electronics retailer, but without written comments. One hobbyist using it with a PCA9685 servo driver reported that it moved to position in small jerky steps, ticking about one degree at a time, and then pushed hard against its target once it arrived, unlike other servos on the same driver.
