Logitech G402 Hyperion Fury Gaming Mouse - Inhumanly Fast

The video begins by introducing the Logitech G402 Hyperion Fury, emphasizing its Delta Zero optical sensor and the Fusion Engine technology. The host explains the concept of mouse acceleration and why Delta Zero aims to provide a perfect sensor with no inherent acceleration, illustrating the testing method with a camera slider rig and a grid overlay to verify movement accuracy. He walks through the Fusion Engine components, describing how the gyro and accelerometer work with the optical sensor to reduce gaps in data at very high speeds, and shares an informal contest with Linus to demonstrate the claimed speed. The reviewer then details the software and hardware options, including dpi settings up to 4000, polling rates, and programmable buttons, noting how the product is more conservative than the G502 but offers meaningful performance metrics beyond simple dpi figures. There is a thorough ergonomic comparison to the G502, highlighting eight buttons, slightly different grip texture, and the overall feel in hand, concluding that the G402 delivers good value at a lower price point. The video wraps with reflections on Logitech’s focus on meaningful performance metrics, a brief sponsorship note, and a closing encouragement to discuss the testing methodology and whether the Fusion Engine and Delta Zero justify the price, while praising the device for offering strong performance without unnecessary extras.
