General Thoughts

The very popular G403 but in wireless form and now upgraded to the HERO version, which means it has their new power saving sensor and actually weighs less. I haven't actually tested the G703 HERO yet but Logitech are pretty solid, especially with their wireless, so we can expect the same performance just with longer battery life, and it's lower weight too. It's an interesting shape, not for everyone, but one I've managed to aim better than others, despite it being much too big for my hand size. Logitech wireless is amazing so if you're after a good wireless gaming mouse, definitely give this one a look.
