Asus ROG Keris II Ace review: Competitive performance

Asus ROG Keris II Ace

We have tested a slew of lightweight gaming mice in recent months. The latest contender in this category is the Asus ROG Keris II Ace. Boasting a 42,000-dpi optical sensor and a wireless polling rate of up to 4,000Hz, this gaming mice is right up there with its rivals when it comes to features. Now these figures probably don't mean much to the average user like me, but I would say that the Keris II Ace is comfortable to use, glides smoothly, and feels accurate in games. And it's a tad cheaper than the competition at S$189.

Quick specs:

  • 54g (without dongle)
  • Up to 107hr battery life (without lighting)
  • Bluetooth, 2.4GHz RF and wired connectivity
  • Up to 4,000Hz polling with receiver, up to 8,000Hz in wired mode

The Asus ROG Keris II Ace has an asymmetrical design that's built for right-handers. It's a design that you often find on these lightweight gaming mice designed for esports players. In fact, the contours of the Keris II Ace are almost identical to that of my Benq Zowie EC2-B mouse. Its profile, though, isn't quite as low as some gaming mice I have seen. Buttons are clicky, and feel consistent — Asus says these optical micro switches are good for 100 million clicks. I also like how tactile the scroll wheel feels, with distinct stops.

At 54g, the Keris II Ace is just as light as Razer's latest Viper V3 Pro gaming mouse. However, the default mouse feet of the Keris II Ace — while larger than some other mice I have seen — are not as gigantic as the ones on the Razer Viper V3 Pro. I'm fine with them — the gliding was smooth enough. But if you prefer something closer in size to the Razer's, you can swap out the default ones with the larger bundled ones in the package. Note that this will increase the mouse's overall weight by a couple of grams.

The Keris II Ace feels comfortable with my usual grip. Groove lines on the left and right sides of the mouse help with the grip. And unless your thumb is significantly wider than mine, the two left side buttons are far enough from my thumb's resting position to avoid accidental presses. I like that some of this mouse's key features (polling rate, DPI and lift-off distance) can be adjusted via onboard buttons, without having to install Asus' somewhat bloated Armoury Crate software. For example, you can toggle between polling rates by pressing one of the side buttons while holding down onto the Bluetooth pairing button at the bottom of the mouse.

Of course, most users will want to install the Armoury Crate app as it offers more comprehensive settings, such as a tool to calibrate the mouse based on the surface and to change the LED lighting scheme. You'll also need the app for firmware updates. But at least if you're using the Keris II Ace at your friend's place or a LAN shop, you can still change the important settings without installing any software.

Like some newer gaming mice, the Keris II Ace offers a polling rate of up to 4,000Hz wirelessly and up to 8,000Hz wired if you use the included ROG Polling Rate Booster dongle. You'll have to plug in the mouse's dongle (ROG Omni Receiver) to the ROG Polling Rate Booster, and then connect the latter to your PC's USB-A port. The ROG Omni Receiver, which fits in the mouse when not in use, can also be used to pair a compatible Asus keyboard and the Keris II Ace. This means you'll just need a single dongle for two wireless devices, thus saving your PC a USB port.

Battery life for the Keris II Ace is comparable with other such lightweight gaming mice. Asus says without the LED lighting you can get up to 107 hours using the receiver (2.4GHz RF connection) and up to 134 hours with Bluetooth. Turning on the LED drops this to 67 hours and 89 hours respectively. This LED will also flash red to warn you when the battery drops below a certain level of charge (you can adjust ths level this in the Armoury Crate).

At S$189, the Asus ROG Keris II Ace is cheaper than the similar lightweight gaming mice from Logitech and Razer that cost over S$200. These mice have similar features and performance, and are great for games that don't benefit from having more buttons. Alternatively, if they all seem too expensive for you, the VXE R1 Pro (under S$60) is a much more affordable option. The Asus ROG Keris II Ace is available now on Shopee and Lazada.
