I bought 5 sets of these for a total of 30 servos. I tested each one, and 3 had problems. One moved but was slow and had no power. Under a light resistance test using my finger. It just stopped moving until I moved my finger out of the way. The other ones that worked correctly would easily move my finger. The second servo would stop responding when encountering the resistance of my finger. It wouldn't respond to any signal from the tester until I gave it a push with my finger. Then it would spin like it should until encountering any more resistance. It continued to fail every finger test in the same way. The third faulty servo would pass the finger resistance test, but failed the range of motion test. When spun counter clockwise it would size up and stop responding to signals from my tester until I nudged it with my finger. It failed the range of motion test in the same way every time. I did not test for torque accuracy, but some servos seemed stronger than others.
The project I'm working on is an 8 legged walking Arduino robot with a grasping arm on top. It is a proof of concept bot for a later bot which will be much larger and hopefully be able to fetch things from around the house or fridge. I'm disappointed in my purchase.
Edit: Seller contacted me and replaced the defective items. I am very happy with my purchace now. I will definitly check here first when ordering more servos. Customer service is world class good.

Lots of torque and easy to mod
I purchased these to automate my ham shack a bit. Blinds, A/C registers, stuff like that. I’m disabled and these will help out a lot. They have plenty of torque. My daughter tried to stop a servo. She didn’t have a chance. She’s no lightweight either. She snapped a real Craftsman socket when she was 15. They’re easily converted to 360° rotation. With metal gears, several arms, spacers and screws for the price, I’m impressed!

These servos seem like a really good value so far. The metal gears are really smooth and the servos have been reliable for a dozen flights on my plane so far. I don't have any complaints right now. Give them a try.
Good value. Seem really solid so far.
