I pried off the retaining ring with a paperclip, pulled the defective trackball out by touching the magnetic rollers with the end of the paperclip, and dropped the new one back in. All of my trackball problems were solved in 1 minute, without having to remove the faceplate.

This trackball performed flawlessly, although I failed to take into account the effect that the white backlighting would have on a translucent red ball: it turns it slightly more on the pink side than I would have liked, but it is still red enough that I haven’t bothered to order a different color.

If you are particularly sensitive to a slightly pink hue then the red isn’t for you: otherwise this product gets a shining review.
