With the Avior Pro, Mionix also updates their only ambidextrous design: PAW3370 sensor, Kailh GM 8.0 switches for the main buttons, pure PTFE feet, and a flexible, braided cable.
All of their Pro mice are so heavy, it's sad that Mionix doesn't really see how the gaming mice market works today. I used to be a big fan of the Castor and seeing a fresh modern version of it would be super cool, but yeah it's a bit too heavy now with all of them lighter mice nowadays.
