Miuzei 20KG Servo Motor High Torque RC Servo Metal Gear Waterproof for 1/8, 1/10 R/C Model DIY Car Robot, DS3218, Control Angle 270° 

This is a very heavy duty servo. Very high torque from this guy. Would be great for larger heavier builds. Noise level is a little loud but is as much as you would expect. Functions great just make sure it is the right size for your build. Would fit great in larger builds. Other wise a great value for the beefy motor.

Works great

Works better than a lot of name brand

Strong enough to hold steady and turn well at higher speeds (40mph). Turns fast enough but speed could be desired. As usual the supplied metal arm was too long so I filed it down with a grinder and it work great. I put the 20kg in a Bigrock on 3s. 👍🏻

Very good value. Comes with several different actuator arms for automating just about anything. Very well made. I used this one to upgrade an outdated steering system on an RC car. Worked very well

I bought three of these servos. The hardware appears to be quite robust, although I'm not doing anything requiring a lot of torque. My units came with three screws, one larger one that can be used to attach the arm to the servo, and two smaller-diameter screws that don't seem to fit anything--they are too small to attach anything to the arm. They also came with zero documentation although some of the specs can be found online. But some useful information appears to be unavailable like: The overall period for the PWM signal, the current requirements on the control lead, whether or not the control lead can operate at 3.3 V (I'm using a Raspberry Pi).

So far so good!! Love it

For 15$ killer deal Works great not issues at all im really impressed with this
