Reviews (2)
Includes 2 reviews aggregated from around the web.
A comparison of clones singled it out as a good one with real digital performance, although the genuine TowerPro feels a little smoother. Marketplace listings show about 4.8/5 and high recommendation rates. As with all MG90S-class servos, positioning is not very precise.
