Power hungry: 2.5x compared to more expensive equivalent digital servos under load. Same consumption under no load, but many times they keep hunting for position even under no load, so current remains high.

Reasonable speed with some glitches in the feedback pot (vibrating at some positions).

Visible case deformation when servo is in operation under small mechanical load.

One curious thing is that the servos can rotate continuously if forced manually, but they do move 90deg when plugged.

So, they do work, but I would limit the use to slow flyer foamies (they are probably perfect for this). Not for DLG or applications requiring precision and low power consumption.

Nice small servo. Good quality products. Delivery 11 days to Slovakia. Thanks
