Today we have another lightweight gaming mouse from a company you might have heard of, Mountain.  Mountain jumped onto the scene last year with their Everest modular gaming keyboard.  The Makalu 67 is their first gaming mouse and it is named after the Makalu mountain, which is actually the fifth highest in the world.  This is a lightweight gaming mouse and as the name suggests it is only 67 grams!  Beyond that you have the PixArt PAW3370 sensor and OMRON switches.  The mouse is definitely larger than many of the lightweight mice we've reviewed in the past, but still is able to remain very lightweight, let's take a look!
