very simple, works great.
Using this to bench test motors common to FIRST robotics compeition, CIM, BAG, 775, etc. Just like an RC controller PWM, 1500pwm is neutral, 2200 high is forward, 800 low is reverse. Very simple. Having the screen is key for actually testing motor outputs in mid ranges. Will definitely buy more of these for the lab, and my own drone motor use.

Saved me a lot of time
I purchased this to test multiple servos on a project, and I'm glad I did, because before I reassembled everything, I found that one of the servos was not functioning properly. Saved me a lot of time.

Decent cheap servo tester
Bought this while building a new RC plane and it was very convenient having this to position my servos precisely when installing the control linkages. One of the plugs on mine appears to be dead so I can only test 3 servos at once instead of 4, but that's not a big deal. Overall it's a decent cheap servo tester that gets the job done.
