The Bottom Line The Mad Catz Cyborg R.A.T. 9 is the most expensive gaming mouse we know of, but its vast customizability, unique features, and strong performance make it a worthwhile expense for demanding PC gamers.
Easily one of the most distinctive-looking mice we've reviewed, the Mad Catz Cyborg R.A.T. 9 is aimed at dedicated PC gamers. This wireless device boasts the highest degree of customizability we've seen in a gaming mouse, along with the highest price tag, coming in at $149. The price will drive off all but the most committed gamers, but for those willing to pay, the R.A.T. 9 will provide an unparalleled level of input control.
Even in an office full of seasoned tech journalists, the R.A.T. 9 spurred more than one person to exclaim, "Whoa, what is that thing?" Despite its mechanical appearance, this "thing" includes many of the familiar trappings of high-end gaming mice. It comes with a customizable 5,600-dots-per-inch laser sensor, a weight kit, a button dedicated to on-the-fly dpi adjustments, and a pair of thumb-side buttons to give you a few extra in-hand control options.
Mad Catz actually has a whole family of Cyborg R.A.T. gaming mice. The wireless R.A.T. 9 is the most expensive, but if you prefer wired mice, the R.A.T. 7 is otherwise identical and costs $25 to $40 less.
