Review on 4Pcs ES08MA II 12G Mini Metal Gear Analog Servo Shockproof Stable Machine For RC Model - RGBZONE by Anna Crane

I usually don't mind using knockoffs but I used one of these for the tilt servo for a pan tilt camera mount and it was very jerky like the resolution was half of a genuine EMAX ES08MA II. This may not be noticeable if you don't need the finer resolution but for a camera mount it was terrible. I dug around and luckily had a genuine EMAX ES08MA II leftover from a previous purchase and it worked perfectly; Very smooth. Consequently I discovered the only physical difference between the two is that the servo spline on a genuine EMAX ES08MA II is smaller than this knockoff.
