[M] SteelSeries Aerox 3 Wireless Ultra Lightweight Wireless Gaming Mouse Review
 

After configuring the Aerox 3 Wireless to our liking and using it for a few hours, we were quite amazed to see how light the product is, considering that it also houses a rechargeable battery! The lighting is well spread on a large area by using only 5 LEDs, thanks to the included diffuser and the battery life is maximized via quite a bit of power management features, configurable from the SteelSeries Engine 3 GUI.
