ToolkitRC ST8 Advanced Multi-Servo Tester
This servo tester has a lot of fancy features, but seems to lack some basic ones!

The biggest miss is that it is fiddly to set each servo to a unique value. When using the P1 knob, there is no option to quickly isolate control a specific servo. If you want to use the P1 knob, it will simultaneously control all servos set to P1 knob control. The only way to adjust servos to individual positions is using the 'key' setting which does allow for setting three different values per servo. There is no option to invert the input signals or servo outputs.

The tester does work well for testing and graphing servo current draw, but only provides a maximum current reading. It would be great to read a value of the average current draw, as the maximum current spikes are brief.

Adjustable output voltage is another good feature.

It does seem that many of these issues could be resolved with improved firmware, however there have been no updates since V1.13 2020-07-21.
