The Logitech G903 HERO is a great gaming mouse. It's an upgrade over the Logitech G903 LIGHTSPEED because it features the HERO 25K sensor, which provides a very wide CPI range that you can adjust in small increments. It has low click latency whether you're using it over its USB receiver or wired, it has a high maximum polling rate, and the sensor remains consistent when moving at a fast speed. It's well-built, glides smoothly, and its ambidextrous design should feel comfortable for most people using any grip. Sadly, it's heavy and not designed for ultra-light gaming, but it comes with a 10-gram weight if you want to make it even heavier.
