Ultra-lightweight 66g build

The Aerox 5 weighs 66g, making it one of the lightest gaming mice available. This low mass allows rapid swipes and reduces fatigue during extended sessions in fast-paced titles.

IP54 AquaBarrier and 9 programmable buttons

An IP54 rating protects the internals from water splashes and dust ingress. Nine programmable buttons, including a five-button side panel and a dedicated up/down flick switch, are configured through SteelSeries Engine software.

Competitive gamers needing low weight

Suits players who prioritise minimal weight and durability against spills. Buyers who want a heavier mouse, wireless connectivity, or more than nine buttons should consider other options.

Questions about this item

How long do the switches last before they need replacing?

The mouse uses optical switches rated for 80 million clicks, so replacement is unlikely during normal use.

What limits tracking during long gaming sessions?

The TrueMove Air sensor handles up to 18000 CPI, 400 IPS and 40G acceleration without smoothing or tracking loss.

How warm does the shell get after hours of play?

The open honeycomb shell stays close to room temperature because air flows through the 66g frame continuously.
