Reviews (6)
Includes 6 reviews aggregated from around the web.
There are few reviews for this servo on the web. Five eBay reviewers call it a great, affordable, tiny servo for light jobs in tight spaces, with one warning that removing the arm can pop the top off and let the gears fall out. A DLG test site gives it top marks for centering and speed.
