For a serious ultra-lightweight wireless gaming mouse today, the “acceptable” weight is around 60 grams—in part because the mouse still feels rigid and substantial in-hand. Corsair's new Sabre V2 Pro Ultralight clocks in at only 36 grams; compared to big names like Razer, Logitech, and SteelSeries, this mouse is only two-thirds the weight of their lightest models. Next to smaller, competition-focused companies like Hitscan, the Sabre v2 Pro is neck-and-neck. The Sabre v2 Pro Ultralight costs $100 and is available in black and white. In a similar way, Corsair's new gaming mouse is unbelievably light.
