“For the size and price you can't expect much better.
Two points to note though. First, Ive used over 20 of these servos, and none had 180deg movement. As noted by another reviewer the real range is less; typically around 160-170deg. If you try to push them beyond this they stall/strain. Secondly, all the servos I've used have slightly different max ranges and even sound quite different.
These are not big issues, but you should be aware of them so you can design around the variability.”
“moves from 0 to 170 degrees (instead of the approximately given 180). On the Arduino the out of the box Servo library and SoftwareSerial don't play along nicely – not the fault of the servo though :)”
