The Big Brother Swirly.. Is it supposed to be responsive?

So, I’ve had this Swirly from Big Brother for a while now. I think I traded for it, and at first I know it was unresponsive. Soon after it started acting somewhat responsive. When it started, I opened it up and noticed that the silicone was damaged (I’ll include a picture if I can figure out how to). It took me years to finally start wondering if it is supposed to be responsive. Also, could anyone explain why it was discontinued?

Discontinued? Probably because the company went out of business. Responsive? I highly doubt it’s supposed to be responsive my friend, try replacing the pads/cleaning the bearing.
