Razer's had a good thing going with its DeathAdder gaming mouse. So much so, that it's left the peripheral largely untouched, varying only its color over the years and adding a left-handed edition. Which makes today's refresh notable, since it brings a major update to the mouse's optical sensor -- now 4G -- that should improve accuracy with a resolution maxing out at 6,400 dpi. The unit still retains the same form and function as the original, although a textured, rubber grip has been added to the sides for increased comfort. And in keeping with tradition, gamers can also sync this mouse with the company's Synapse 2.0 software to access firmware updates, as well as settings for button mapping across titles. It's available now for $69 / €69, so hit up the source below to get your order set.
