My current trackball has lost its smoothness and feels “sticky” no matter how well, or often I clean it.

So, I’m looking for a trackball (thumb controlled) with the following features:

• Bluetooth wireless with support for at least two connections (for laptop and PC media station).
• Uses AA or AAA batteries.
• Uses bearings.
• Set at a tilt/ergo angle.
• Repairability is also important, but not a total dealbreaker if the mouse is high-enough quality.

So far, most that I’ve found will lack one of those features, but I’d really like to have all of them, if possible.
