After previously reviewing the ASUS ROG Gladius II Origin, there was pretty much no space for big surprises. That mouse was and still is a great product, and I expected nothing less of the Wireless edition. Thankfully, there is pretty much nothing I could objectively nitpick on—the Gladius II Wireless is great in almost every aspect.

Shape is king, and should be among the very first aspects when choosing a mouse. Gladius series mice all share the same robust right-handed ergonomic, high profile shell design that is mainly going to fit palm grippers with larger-than-average hands (this is just a basic guideline and should not be taken for granted). As for the materials and surface coating, the Gladius II Wireless is quite fantastic in my opinion; the sides have textured rubber grips, while the top has a semi-matte surface coating (but again, what I like you might dislike, and vice versa).

When it comes to build quality, this mouse isn't perfect, but it doesn't really have anything to be ashamed of. The scroll wheel can rattle slightly around in its place if you shake the mouse (it's not nearly as bad as with the Gladius II Origin), and the shell emits quiet creaking noises if you press down on it with great force. None of these impact performance, nor can they occur during regular use. Unfortunately, the mouse is rather heavy, weighing about 125 grams on my scale, which is a lot, especially compared to some other high-end wireless mice in the market nowadays.

Buttons are great on this mouse, and the main ones feature ROG-exclusive socket switches, which means the micro switch under the button can be changed without soldering. This is a truly remarkable feature as main switches are usually the first things to break on a mouse. The scroll wheel uses an Alps encoder, which provides tactile feedback, and the steps remain nice and light. Moving on to the mouse feet, there are four small skates on the bottom plate's corners, and they provide a smooth glide with hardly any friction. There are no replacements in the box unfortunately, so once these wear out, you have to go for aftermarket models. The cable is thick, stiff, and braided; it creates a lot of drag and resistance, which I still don't understand on gaming mice as they should be the exact opposite.

Sensor-wise, the Gladius II Wireless shows a stellar performance. The PixArt PMW3389 does a fantastic job by providing raw, snappy, and perfectly accurate tracking. As far as smoothing goes, I wouldn't recommend using the mouse on or above 1900 CPI if you play online games on a competitive level.

Wireless tech is becoming better and better each year—we get more and more ultra-low latency wireless products, and thankfully, ASUS has joined this bandwagon as well. The Gladius II Wireless roughly has 1 ms of input lag without its cable attached, which is remarkable and not very common among gaming mice—it seems like Logitech's monopoly is finally coming to an end in this market segment. As for the battery, it provides more than enough power for a few days of intensive use on 1000 Hz with one charge. If you switch to Bluetooth (I really don't recommend you do so for gaming, but it's fine for browsing), battery life gets even better, especially if you turn the lighting off.

Speaking of lighting, the Gladius II Wireless has quite a lot of RGB features if you favor eye candy in peripherals. The lighting looks fantastic, with vibrant, bright colors and super-smooth transitions. The ASUS ROG Armoury software lets you tweak around with all the usual settings, including button remapping, macro-writing, profile switching and, of course, fiddling with the sensor settings. Not a lightweight program, it still doesn't consume a lot of resources while running in the background.

All of these great features don't come cheap, which translates into quite a hefty price tag. The Gladius II Wireless costs $110, which is a staggering amount of money for a mouse. However, if you take a look at the competition (especially talking about the low-latency wireless models here), it's more than fair. If you really wish to let go of wires, don't mind the weight, and find the shape suitable, I can absolutely recommend it; moreover, it definitely deserves to be an Editor's Choice.
