The Viper V3 HyperSpeed has an approximate size of 127.1 x 63.9 x 39.9 mm (L x W x H), so we are dealing with a medium-size chassis, while the weight is 59g without the battery installed…this reaches about 82g with the battery inside the mouse. The textured plastic and shape allow for a comfortable grip and we felt right at home when using it while gaming in New World, Escape Simulator, Tauri WoW, ArcheAge and The Last Of Us Part I. The tracking is flawless and we have also noted no latency when actuating the buttons.
