CMStorm Sentinel III Gaming Mouse Review

For my testing, I chose to use the CM Storm Sentinel III as my main mouse over an extended period of time, replacing my Roccat Tyon. Real world testing scenarios are particularly important when it comes to peripherals as there is no straightforward way to assess them.

First we will take a look at Cooler Master’s Mouse software, which will let us delve into all of the additional customization options.

Sentinel Software Main Screen Sentinel Software Key Assisngment

Upon opening up Cooler Master’s mouse software, you will be greeted with the key assignment window, where you can make quick adjustments to different functions. The next screen allows you to set up the Sentinel III’s ‘TX’ key which will allow you to bind multiple functions to one button.

Sentinel Software Lighting Sentinel III Lights On

The next tab lets you set up the lighting on the mouse. Since the LED is RGB, you can select almost any colour you want and pick from a few effects. Unfortunately, I didn’t find the Sentinel III’s lighting to be as impressive as other mice I’ve reviewed as there is only one lit zone. However, not everyone gets excited about fancy lighting so this will come down to personal preference.

Sentinel Software DPI Settings Sentinel Software OS Sensitivity

The next tab will let you adjust your DPI settings for different profiles. Your exact DPI will also show up on the OLED screen on the mouse, this screen can also display your profile so you always know exactly what your mouse is set to without opening up the software.

The next window controls OS functions like polling rate, sensitivity, button response time and double click speed. These options will be locked by default and controlled by Windows but you can change this if you want.

Overall, Cooler Master has developed a nice little software package here, I found it to be responsive and options didn’t take too long to change after hitting the ‘Apply’ button- which can be an issue with some mice.

Now let’s talk a bit about comfort and usability. This mouse is designed with palm grip users in mind as you can tell by the shape. While this is great for right-handed users, it does leave left-handed users out entirely, which is worth noting.

As a palm-grip user myself, I found the mouse to be shaped perfectly, fitting in my hand well with all of the buttons easily accessible. Speaking of which, the side buttons, as well as the left and right mouse clicks all have a nice tactile feel to them once pressed- the switches don’t feel mushy at all.

Not everyone makes use of additional mouse buttons while gaming but I find them to be particularly useful for quick weapon switching in shooters like Counter-Strike. I also like to use the back side button as my dodge in The Witcher 3: The Wild Hunt. The two buttons on the side of the Sentinel III were placed well, allowing my thumb to reach both with ease.

Aside from being extremely comfortable to use, Cooler Master’s CM Storm Sentinel III also has an excellent sensor. I had no issues with tracking on both cloth and granular mouse pads, as well as the wooden surface of my desk, which is all thanks to the new and improved Avago 3988 sensor.
