Logitech's G900 is meant to alleviate your concerns about wireless gaming mice.

Wireless mice have gotten to the point where they're basically as reliable as wired mice, but people still don't trust them as much as they might want to. And they reallywant to; consider the gadget known as a mouse bungee, which elevates a mouse's cable to eliminate the possibility of it getting tangled up with the mouse. So if you're a serious or even professional gamer, and you could go wireless and still get the same level of performance — and if money were no object — why wouldn't you?
Well, you might say, a wireless mouse will always be somewhat laggy compared to a wired one. A more anxious person might respond, I'd be terrified of the battery dying during a close game, and what if I left the USB dongle at home? And the speed demons of the esports world might note, If there's a built-in battery, the mouse is inherently heavier.
To address all those issues, Logitech set out to make the ultimate wireless mouse: a device that would meet or even exceed the reliability of wired mice, and simultaneously dispel the myths surrounding wireless mice. A team of 75 to 80 people across multiple continents has been working on that goal for the past three years, and Logitech is finally ready to present the fruits of that labor to the world: the Logitech G900 Chaos Spectrum.
