I use them to complete the writing of the drums. The sensitivity, as expected, is not the best, but in principle it is suitable for this price. I don't create bits, so I can't say for sure about this, maybe it will work. I could barely find the application on my computer, there are no instructions (there is one small piece of paper, but nothing is clear there) and there were no download links either. After half a year, the upper part began to peel off, but there were no electrical circuits, there was a simple layer of plastic, so I just put it on super glue. Well, you can play it, but forget about the sensitivity. It is there, but it reads very poorly. With the same force of impact can give different levels of pressure
