The ASUS ROG Gladius III Wireless is a right-handed, wireless gaming mouse with two buttons on its left side. It's suitable for most hand sizes, but small hands may struggle to reach the forward side button using a claw or fingertip grip. It's made of matte black plastic and is somewhat light, and it has RGB zones in the scroll wheel, its left side panel, and palm rest logo. You can connect it via its USB receiver or Bluetooth, and you can pair it with up to three devices. Performance-wise, it has low click latency, a very low lift-off distance, a very wide CPI range, and you can adjust the CPI in increments of 50. Unfortunately, while the sensor on our unit is consistent, it's fairly inaccurate. However, you can offset this by setting your preferred CPI a bit higher to compensate. Also, while you can reprogram most buttons on the mouse, you can't set macros, which may disappoint some users.

Compared To Other Mice
The ASUS ROG Gladius III Wireless is an update to the ASUS ROG Gladius II Wireless, with a few upgraded aesthetics and performance differences, which include a much lighter weight and rounder edges on its L/R click buttons. Also, its side panels are textured plastic, and there's a laser-etched text pattern on the left side to let RGB lighting pass through. It has some rare features that most gaming mice lack, like hot-swappable L/R click button switches and on-the-fly CPI adjustments using its scroll wheel. It has low click latency, though some people may prefer an even more responsive-feeling option. Unfortunately, while you can reprogram most buttons on the mouse, you can't set macros like you can on other gaming options, which may disappoint some users.

Test Results
ASUS advertises that the battery in the ASUS ROG Gladius III Wireless should last up to 55 hours when used with the receiver and up to 85 hours when used over Bluetooth, both with the lighting off. You can pair the mouse with three devices via Bluetooth and cycle through them with the "Pair" button on the underside.

You can program most buttons on the ASUS ROG Gladius III Wireless, excluding the Pair button and Profile button on the underside, as well as the left click. The Pair button lets you switch between three Bluetooth devices, and the button behind the scroll wheel lets you cycle between four CPI settings. You can also adjust the CPI on-the-fly by pressing the CPI button for three seconds and scrolling up and down. The L/R click buttons' switches are hot-swappable, and the mouse comes with alternate switches to replace the proprietary ROG Micro Switch switches already installed.
The polling rate options available on the ASUS ROG Gladius III Wireless are 125Hz, 250Hz, 500Hz, and 1000Hz. When using Bluetooth, the polling rate is limited to 125Hz. Unfortunately, the sensor is very inaccurate, and it undershoot the set CPI by 11.94% during slow movements and 17.22% during fast movements. However, since the sensor is fairly consistent, you can offset the inaccuracy to a degree by setting your preferred CPI to 12-17% higher than you typically would to compensate.
The software for the ASUS ROG Gladius III Wireless appears to have an option for setting macros, but the option is grayed out and doesn't function.
