Cooler Master CM Storm Sentinel Z3RO-G Twin Laser Gaming Mouse Review


The CM Storm Sentinel Advance was a favorite among gamers for its comfort and ease of customization. It was, however, plagued by a faulty twin laser that caused issues with tracking and liftoff. By tweaking the 5600 DPI twin laser system and doubling the on-board memory to 128kb, Cooler Master has delivered a mouse that is a solid improvement over the Advance. Cooler Master's patented Storm Guard security and Sentinel-X software round out the package, making the Sentinel Z3RO-G a force to be reckoned with.



This technological marvel utilizes the latest innovations in cutting-edge technology: 5600 DPI twin laser, rapid fire mode, 128kb internal Sentinel-X™ memory and our patented security, Storm Guard™; The Sentinel Z3RO-G is designed for one purpose and one purpose only - to search and destroy.

The Sentinel Z3RO-G ships in a box sporting the signature CM Storm colors. A flap opens to give buyers a glimpse of the mouse and a list of impressive specs. The Sentinel Z3RO-G comes bundled with a free copy of Shattered Horizon, giving gamers a chance to jump into the fray with the newest addition to their arsenal.

The mouse feels like a precision instrument in the hand thanks to its sturdy build, braided cable, and soft-touch finish. Cooler Master goes the extra distance by including a replacement set of slick Teflon-coated feet. The mouse fills the hand nicely and instills a sense of firm control much like its predecessor. The weight system, independent LED zones, and OLED display have all been carried over from the Sentinel Advance. Apart from the new grey and black motif on the Z3RO-G, the two mice are identical in appearance.

The Z3RO-G comes with an intuitive 8-button layout. Two small buttons behind the scroll wheel allow users to switch the DPI setting on-the-fly, with the current XY-sensitivity settings being reported on the center OLED display. The two side buttons are well-sized and easy to actuate, however for those with smaller hands, you may find yourself reaching for the front one a bit, and with bigger hands you shouldn't have an issue. The scroll wheel is rubberized and depresses easily under firm pressure, and has a firm scroll. A small center button at the front of the mouse gives users control over five profiles, with each profile identified by a corresponding LED color: red, blue, purple, green, or teal. We're not sure why Cooler Master didn't take advantage of the 128kb of memory to give users access to additional profiles, as such a feature would have made the Z3RO-G a clear upgrade over the Advance.

Underneath the Z3RO-G, users will find an improved 5600 DPI twin-laser with independent XY-configuration, as well as a foam lined compartment for the set of five 4.5 gram weights. The weights fit very snugly and are easy to reposition, but lack the fine adjustability in left-right weighting that we've seen in other mice.  For those who like a very heavy mouse, say a past G5 user, the weights may have an added bonus.





Apart from a refreshing teal and black color scheme, the Sentinel-X control panel that interfaces with the Z3RO-G is no different from the Sentinel Advance panel. As the software already offers a buffet of options for customizing the Z3RO-G with ease, we're glad that Cooler Master didn't make any changes here. We were able to set up some custom profiles, set independent LED colors, and apply a custom clan logo in Bitmap form to the mouse in a matter of minutes. This gave us more time to play with the script and macro editing features, which are exceptionally simple to setup.



Final Thoughts

Overall, we found the Sentinel Z3RO-G to be very comfortable and accurate. The provided script editor opens up endless possibilities for executing complex commands with a single click, and applying clan logos to the crystal clear OLED is a breeze. Anyone who hasn't previously owned a Sentinel Advance will love using the Z3RO-G. But those who have already played with the Z3RO-G's predecessor may be disappointed by the lack of upgrades. While Cooler Master has fixed the problems that plagued the original twin laser system, doubled the amount of onboard memory, and given the mouse a different skin, the Z3RO-G is the same animal.  We found the sensitivity setting readout to be very helpful, in case you forgot the particular settings in a given profile, and the OLED screen looks great.  The software offers much versatility to make it work for you in games with macros or fine-tuned sensitivity settings, and is certainly a top-notch gaming peripheral.

The Bad

  • OLED readout of sensitivity settings
  • Simple control panel with tons of options
