Known primarily for producing cables, adapters, and other PC and A/V connectivity kit, Iogear has begun its entry into the crowded field of gaming peripherals in an attempt to unseat some of the best gaming keyboards and best gaming mice. A subsidiary of Taiwanese parent company ATEN International, Iogear has targeted a very specific interpretation of 'gamer' aesthetic with its accessories, leaning hard into rainbows of RGB lighting and sharp, futuristic angles and materials, and the Fokus 2 is the pinnacle of that trajectory.

It begins with a precision cast aluminum frame, which partially explains the weight of the unit. The Fokus 2 is a heavy mouse, weighing in at 130g even without the durable, braided cable, and for many this will likely be a deal breaker. If you prefer a sparrow-weight mouse designed to fly effortlessly across your desk, the considerable bulk of this pointer will be an immediate turn off. But if you don't find a little additional heft offensive, and particularly if you have larger hands, the Fokus 2 is a great fit. Personally, I like a mouse that feels substantial and dense, and the few extra grams won't fatigue your hand during use.
