Was gonna recommend the Logitech X2 Lightspeed up until that last sentence. Logitech on the mouse side make solid products nowadays and I'm very impressed by the performance and quality straight through on the X2.

Bit late, but my SteelSeries Rival has lasted me almost a decade now without any issues. They also have wireless models now. They're one of the heavier mice out there and some models have swappable weights.

It's very reliable and has pretty decent software (works fine without the software too). It's gotten me through many years of competitive FPS games.

Steelseries arctis 3 wireless is fantastic (running on AAA bateries). At first it felt too light, but after putting bateries in, it somehow gets perfect balance.
