The Attack Shark R5 Ultra pairs an ultra-light 39 g hollowed carbon-fibre shell with high-end specs (PAW3950-series sensor claims and up to 8000Hz polling) and Omron 100M switches; it’s a nimble, low-mass gaming mouse with included skates and grips but is marred by firmware/driver shortcomings and at least one serious marketing mismatch around switch type. Good for competitive fingertip/claw users who prioritize sub-40 g weight and low-latency polling; exercise caution due to software and advertising inconsistencies.
Buy if you want a sub-40 g, low-latency competitive mouse and can tolerate limited firmware support; avoid if you need guaranteed optical switches or robust Mac/driver tooling.
