Hi Pimoroni Team,

Thank you for your great DIY items!

I just recently got PIM447 trackballs. But the latest one isn’t smooth as it was.

then I found ball color is different.

![image](https://us1.discourse-cdn.com/flex016/uploads/pimoroni/original/2X/5/5a9030d3597e20972e9ccdfca84194d6ef76a0c4.jpeg)

Is there any product change?

Thanks

You might need to @ one of the Pimoroni folks, like Hel or Gadgetoid. Or maybe email support (at) pimoroni. Com?
