Our Verdict

ATK Blazing Sky U2 Ultimate

ATK Blazing Sky F1 V2 Extreme

The ATK Blazing Sky U2 Ultimate and the ATK Blazing Sky F1 V2 Extreme are lightweight wireless gaming mice. Both mice deliver similarly remarkable raw performance suitable for competitive gaming at any level, but the F1 V2 Extreme is ~15 grams lighter. The U2 Ultimate's shape is better suited for claw grippers with its wide, rearward hump, while the F1 V2 Extreme has a smaller, more moderate shape that's suitable for a variety of grip types.
