The Elite adds new, larger feet to the underside, with a ring around the sensor, which should keep the mouse skating well even after months or years of wear.
There’s no "right" weight for a mouse, necessarily, but I’ve talked to pro gamers who play Counter-Strike, Starcraft, Battlefield, and other games, and they almost universally recommend the same thing when it comes to gaming mice: the lighter and simpler the better.
Fewer buttons are generally better than more buttons, which can over-complicate the design of a mouse or make it harder to grip.
A lighter weight means you can make more precise movements more quickly with less exertion.
The buttons sit just above a large rubber grip pad that helps keep your thumb anchored on the mouse at all times, and they can easily be pressed without repositioning your thumb.
It has a large, well-notched scroll wheel, and two large buttons on the left side of the mouse that feel satisfying to click, but are stiff enough to prevent accidental presses.
Personal preference matters, but not all mice are created equal.
There are many, many bad gaming mice out there, with sensors that aren't up to snuff, terrible driver software, or cheap build quality.
We've used dozens of gaming mice to pick out the best you can buy for different hand sizes, grip types, and gaming preferences.
The Razer Deathadder has the best shape of any gaming mouse I've ever used, and I’ve spent a few hundred hours playing games, using Photoshop, and browsing the Internet with it over the years. The Deathadder Elite uses a 16,000 CPI optical sensor, but big numbers don't necessarily mean much when it comes to mouse specs.
