In another thread ( [Buying replacement diffuser? - #3 by beams](https://forum.clockworkpi.com/t/buying-replacement-diffuser/23320/3) ), beams mentioned a source for original Panasonic jog balls, from which I immediately ordered a couple. Today I’ve fitted them to both of my uConsoles. They do indeed operate more precisely than the ones supplied with the uConsoles. Although I was already satisfied with the supplied jog balls – in conjunction with the QMK firmware – I still notice an improvement. In my opinion, the movement of the ball is detected more accurately, which sometimes also results in a higher cursor speed. I have reduced the speed accordingly in the control centre. The surface of the balls also appears to be more grippy and has a more pronounced matt finish than that of the balls on the supplied jog balls. I suspect that the magnetic axes are stronger and/or more precise, which, combined with the rougher surface, results in greater accuracy. So if you’re looking for a new jog ball anyway, you might want to give Panasonic’s a go. --- _[View the full topic](https://forum.clockworkpi.com/t/evqwjn007-trackball-troubleshooting-fixes-and-mods/21031)._
