Razer Deathadder/Deathadder Chroma
Razer Deathadder/Deathadder ChromaI have the chroma version and its very comfortable, fits my hand nice, and has little grips on the sidesor if you wanna go all out get the Logitech MX Master, which is on sale on Newegg for $70 right now iirc.
this is a good mouse... until the mouse wheel wears inliterally its only issue. i believe i have an outdated blue-led model, but it's still a deathadder and the wheel on it malfunctions now. when i scroll up, it tries to scroll down at the same time. it doesn't scroll down every time, but it still does it enough for it to be annoying. sometimes it won't register the wheel at all.
i have that exact one but theres only one problem: ive had it for less than a year and already the lights are starting to wear outgg razer
