The ROCCAT Kain 200 AIMO wireless gaming mouse is a good high-end option. It has two buttons on the left side and feels well-made. It connects via charging cable or wirelessly via its USB receiver. Its ergonomic, right-handed shape is nearly universally well-suited to all hand sizes and grip types. It has a very short lift-off distance, a wide CPI range, and you can adjust the CPI in 100-point increments. Unfortunately, it has a higher click latency than most other high-end wireless gaming mice. It’s also quite heavy, has no internal storage for its USB receiver, and its mouse feet don’t glide as smoothly as those on comparable mice.
The Kain 200’s pair of side buttons were also just as easy to reach and press as the Kain 120’s, if only because they were in the same location. They’re set to go forwards and backwards in your web browser by default, but you can assign them to a variety of functions by downloading Roccat’s Swarm software, including macro commands, media controls, hotkey shortcuts, opening folders and applications, and cycling through different DPI or sensitivity speeds.
The mouse has a good amount of height, and the smoothness of the chassis feels good in my palm when it makes contact, but the hump doesn’t align perfectly and fill the cup of my palm like the MSI Clutch GM30. The Roccat Kain 200 Aimo, on the other hand, stands 1.69 inches (4.30cm) tallest, while the MSI stands 1.38 inches tallest. The Roccat Kain 200 Aimo is also slightly shorter and wider than the Clutch GM30 (4.88 x 2.56 x 1.69 inches versus 5.03 x 2.01 x 1.38 inches), which affects the placement of the hump.
The 3.70-ounce Roccat Kain 200 Aimo is built similarly to similarly specced wireless mice such as the Razer Basilisk x HyperSpeed (5.11 x 2.36 x 1.65 inches, 2.90 ounces) and Corsair Ironclaw RGB Wireless (5.5 x 3 x 1.6 inches, 4.59 ounces), but its shorter length makes it feel more portable. The white design of my review unit also made the mouse appear lighter. However, more height or shifting its tallest point closer to the back would have improved the comfort of some palm grippers during long gaming sessions by providing a more accessible place to rest those palms.
