Looks like a good product, with Logitech, the built quality should be good. I can see the need for this

this makes so much sense.

"With POWERPLAY™ and LIGHTSPEED™ technology, Logitech G has solved the barriers to high performance wireless gaming. Input lag, wireless disconnects, and dead batteries are now a thing of the past. Welcome to the future of wireless PC gaming, achieved through advanced science and unrivaled engineering. Logitech G invented LIGHTSPEED wireless technology to deliver the ultimate in high-performance wireless gaming. LIGHTSPEED wireless technology is as fast or faster than many leading competitor’s wired gaming mice. So you get the freedom of wireless with no compromises."

I'd be interested in this. Don't know how good/precise are Logitech mouses, I should try.
