The Akko Dash Ultra is a gaming peripheral available in black or white. It comes in two distinct editions, each with different optical switches. The Omron Optical edition features Omron D2FP-FN2 switches rated for 70 million clicks, while the Akko Custom edition utilizes Akko custom optical switches rated for 150 million clicks.
Although both versions employ PixArt’s PAW3950 sensor, there are performance differences. The version with Omron switches is capable of a higher CPI range, reaching up to 42,000 CPI, compared to the Akko Custom edition, which is restricted to 30,000 CPI.
The ambidextrous design gives the Dash Ultra a weight of 44 g. The shell is described as solid, though it contains four moderately large openings at the bottom. Polling rates up to 8000 Hz are supported via both wired and wireless connections. The device incorporates Nordic’s nRF54L15 MCU. This allows for potential battery life of up to 220 hours when operating at 1000 Hz, or up to 28 hours at 8000 Hz using the 2.4 GHz wireless connection; Bluetooth connectivity is also an available option.
Configuration can be achieved through a web driver or specialized software application. Regarding build quality, observations include visible flexing, particularly below the side buttons, and mentions of a loud rattle stemming from the poorly fitted on/off-slider at the bottom. Furthermore, the wireless extender’s metal housing generates surprising warmth when connected to the dongle, and the nano dongle does not slot firmly into either the Type-A or Type-C sides of the extender, potentially causing momentary disconnections.
In terms of button functionality, the main buttons use Omron D2FP-FN2 switches that are noted for their snappy response and metallic ‘ping,’ though these aspects were found to be toned down on the Dash Ultra. The side buttons utilize seemingly unbranded 2-pin switches with low pre-travel and even actuation, but high post-travel.
