The SteelSeries Heroes of the Storm mouse is derived from the Sensei RAW mouse which we have not previously reviewed. This mouse seemed and felt like it was sculpted to be flexible in how it can be held. Its domed shape fits the palm nicely and at the same time, the low height easily allows one to grasp the mouse with a claw grip. The symmetrical ambidextrous design makes the Heroes of the Storm mouse suitable for both right-handed and left-handed mouse users at the drawback of limited ergonomic support under the fourth finger and pinkie when held in the palm. We found using the claw grip to be more comfortable and more effective at controlling the mouse.
