The Microsoft Trackball Explorer is another Microsoft Trackball classic. Not in production anymore just like its brother, the Trackball Optical, this ergonomically shaped trackball offers a fantastic grip and layout, with many buttons, a scrollwheel at the thumb’s position and a proper ball placed in the center. This smooth operator is worth getting, if you can find one.
We can start with the bad news: Microsoft ceased production of this beauty a few years ago. The good news: you can still get a Microsoft Trackball Optical on places like Amazon and eBay. But be fast, because these get more rare everyday! That the current price of an unused Trackball Optical can reach several hundreds of dollars is only another testament to how well this Microsoft trackball was loved.
