Works
Works well but has a quick boot process that triggers any servos that are connected which can cause issues

Worked very well..no jitter..update: yes jitter..
UPDATE:I put on four different servos. The servos DID have minor jitter.These are "tight" servos that follow the commands tightly.BUT, an interesting point; IF,..you put the switch to "neutral position " setting, NO jitter. It appears that when the pot is active, jitter is present. But Not when in fixed neutral setting. The unit still does a wonderful job as intended. , but not "lab" quality. I am still very pleased with it and would definitely buy again. Great for the low price. Buy it if you can tolerate the very minor jitter in "manual" setting.Good product over all. Great value for money.First response: SEE UPDATE ABOVE...Some have complained about jitter. It is because the oscilloscope is triggering on spurious pulses. A very common problem on all testers. However, in actual application , the servos seem to ignore such narrow spurs. But oscilloscopes trigger on such very narrow pulses and cause display jittering. The cure for the scope is to find the best trigger level , and/or set the proper scope settings. When set properly the display showed a very stable pulse.This unit did all channels perfectly and the push button " neutral setting was right on. This is lot of unit for the price.

It works.
For testing purposes of servo, works perfectly. Potentiometer gives a slightly flick but the purpose of this device is not to be precise but to test, then no problem.

No muss no fuss to work out mechanical design with before you put your MCU to work.
With all new DIY ideas its nice to have a tool like this. simple and works so you can see that your design is physically able first. This is a tool the MCU comes after. Works as expected and i have no issue's to report.

Jitter upsets mini servos, but not others
Amended review; Using this for robot prototyping, but in testng the output jitter made mini servos never settle. I concluded it was unusable. Turns out the jitter only upset a certain mini servo type, and that the output works OK for larger servos. Long term durability is TBD.
