Works Great to test servo motor and can even test Brush less motors if you have an esc and dont want to use a bulky controller to test them. Great little tool has 3 modes and has a nice indicator led. Fast Shipping and great price i can recommend this to any hobby enthusiast.

Worked out the box and arrived quickly. Doesn't seem to like the digital servo PDI-6221MG but even Arduino won't work with that unless you use the 16-channel servo driver. Even so the tester is adequately built. Not fancy but has good test routines.

Terrific value and very easy / simple to use. Only time will tell if the fragile casing will prove durable.

40 years I have been using servos, why oh why have I never bought one of these great little devices. I have not stopped using it since I received it..buy one,you won't regret it. 😉

Great gadget to easily test servos with three settings that you can cycle through by pushing a button. Just need a power supply either from where your receiver would normally be powered from or separate 5v battery. I used 3 x AA batteries in a battery compartment with servo wire and plug as a power source.
