Any experience with DFRobot TB6600 drivers?

Does anyone have any experience with DFRobot TB6600 stepper drivers?

From Googling around, it seems that the various TB6600 incarnations are a real mixed bag. The reason I’m interested in this particular model is that its available locally in Australia at a reasonable price and shipping rate.

Thanks for any input
