High recommend for robot project!

I recently incorporated this servo into my personal robot project, and I must say it exceeded my expectations. The 20kg torque provides robust performance, making it suitable for various applications. The full metal gear construction not only enhances accuracy but also extends the servo's overall lifespan. I appreciate the attention to detail, especially with the high-precision potentiometer, which significantly improves accuracy and linearity. It becomes a reliable component in my project, and I would highly recommend it to fellow robot enthusiasts.

Ideal for what it was bought for

Exactly as described! Fast shipping! Strong Performance!

Strong and responsive

These are awesome servo for the prices. What surprise me is , I found that replacing my robot with just one of these , the steering response is much faster than before. everything is okay now. If they do have any problem, l'll update!

Quiet and strong servo

Outstanding performance. Due to my miss operation they stuttered. I thought they were bad and then ask for help. They worked the problem out, and it turns out that my power supply did not give needed voltage. Now they works well.. satisfied.
