I bought one for home and liked it so much I bought another for work. I had previously used the industry standard Logitech MX570, but that mouse is only available in wireless and I was having interference issues if my cell phone was in the same room. This mouse is bigger than the MX570 and fits my hand better with a more natural resting feel. The ball is also bigger, rolls more smoothly then the MX570, and is at least as sensitive. Like all trackballs, this will take some getting used to if you haven't used them before. Thumb trackballs are superior to finger trackballs and offer a more familiar mouse feel without the constant wrist movements. I spend 12 hours a day designing CAD models, and this has helped significantly with wrist and hand fatigue.
Cons:
About half the pressure is needed to press the right click button as is needed for the left click button, making right click very sensitive. This takes a few days to get used to, but isn't enough of an annoyance to drop a star.
Update: Minus one star because the wheel on one of these started to squeak. A little bit of dry lubricant fixed the issue, but still disappointing. I also stuffed part of a folded up sticky note under the right mouse button to make it a bit stiffer, now it feels much better.
