The adjustability works as advertised. I have large hands with very long fingers, and this is the first mouse I've been able to make fit my hand. The mouse seems very solidly built, and all the interchangeable parts are well made. The braided cable is also a nice touch.

The ability to adjust DPI on the fly and create and easily switch between custom profiles is awesome. I'm a cartographer by trade (lots of time in Adobe CS) and a gamer for fun, and the adjustable DPI as well as "sniper" button (which lowers DPI by a percentage you set in the mouse software) are extremely helpful for both. It's hard to imagine going back. I like the horizontal scroll wheel – it's especially good for navigating around large Photoshop and AI files.

Awesome mouse. Wish I'd been using it for years.
