I don't know why people rate this 1 star. It does exactly what it says on the label. The ads that people complain of is literally just the developer asking to upgrade. And it is thoughtful enough not to interrupt you while running the spindle, for example. People just want free stuff these days. Works flawlessly, only gripe is the manual ability to control the spindle speed is missing. But you can use commands for now alternatively.
