Cheap BOB is just like cheap speakers, your putting clean quality pulses in and the rubbish circuitry is degrading what comes out. Still comes out at same or similar speed but now it's all noisy and crackly.! . . . . Defeats the point of External controller..IMO.

The quality of the pulses you put into drive directly affects how smooth the motors work and it's clear to hear the difference when have bad setup.
Thanks!
That was a good explanation..
I guess that's why a good bob costs 50 times more :)
