As the first mouse from Mountain, Makalu 67 presents itself as a quite impressive product, incorporating the latest trends and technologies from the gaming segment; we do get the latest PixArt PAW3370 high-end sensor with a tracking DPI of up to 19000, 1-2mm lift-off distance but also a much lowered error rate versus the previous versions. The ribcage design of the chassis looks more interesting versus the hexagonal hole pattern we have seen with other brands and is much less prone to flex as well.
