Includes 2 reviews aggregated from around the web.
There are very few reviews for this servo on the web. One RC plane flyer says that if he is going with budget servos he gets the Emax ES08D, and a European hobbyist used three of them in a small project alongside a different brand. No failures were reported.

February 10, 2012Application(s): cyclic on a Trex 250 clone. Also, used on a small Pitts bi-plane.
Comments: On the positive side, the ES08D has a very smooth movement and fine-detail to the control. Much more precise than the HXT-900, for example. Really, the servos do work quite well for a while.
On the negative, the potentiometer and/or its circuitry is poor. The servo chatters and buzzes very easily, resulting in heavy wear to the pot and gears. Thus, the negative is that they fail rather quickly.
