We have spent some time with the MasterMouse S while testing it in productivity work but also games, which did include Black Desert Online, Mafia III, Kritika Online and Secret World Legends. The mouse did feel very comfortable during use but regarding the grip modes Cooler Master is mentioning (Palm & Claw), we have only seen the Claw grip usable given the size of the mouse. The Palm grip should only work if you have small hands, but in most cases, it is out of the question. The cable solution coming with this particular model is very sturdy but this fact also implies that it is a little bit rigid so we needed some time to get accustomed with it.
