I have razer deathadder and i have to clamp it with my hand. It is to too small in both dimensions. I tried 20 mice and other are even worse. Can you make something bigger like 140/80 ??? Because there is not single mouse of these dimensions on market... Also i would prefer not to use your drivers as they cause lag and are spyware. Do i have to learn in cad and get 3d scan to make own mouse or what ???
