I’m aware that Logitech G502 Lightspeed is a very pricy peripheral, at $150, but it’s definitely an investment that you’re not going to regret. It comes with pretty much all of the features you would want from a mouse, and more. It’s fast, reliable, and you won’t ever notice that it’s not wired.
By far, the best part of the mouse is the perfect response time in wireless mode; At thins point, everything else is just icing on a cake; It’s also worth mentioning that Logitech recommends that receiver is at most 20cm away from the mouse, for best performance, but that’s not always possible.
It’s a mouse without any significant faults, and I would have to be extremely picky even to identify some; For example, the DPI shift button might be a little to close to the finger, and people with longer fingers might hit it by mistake.
