Cooler Master CM Storm Sentinel Z3RO-G 5600DPI Gaming Mouse Review

The mouse itself takes on an identical form to the original Sentinel mouse although they are finished in slightly different colours. The original version was constructed entirely from matte black plastic whereas the new Z3RO-G version has taken on a grey rubberised paint finish.  This lets you grip it more securely and makes the mouse feel more sophisticated.

CM Storm have retained the matte black plastic for a section on the top of the mouse which includes the left and right mouse buttons and the area immediately behind.  Down the middle there is a strip of gloss black plastic which contains the mouse wheel and DPI buttons, located in front of a small OLED display which displays the DPI levels.

The mouse wheel feels quite refined although it provides a bit too much resistance for our liking.  This makes it a little cumbersome when scrolling through long documents or web pages.  The click action of the mouse-wheel is the most disappointing part, though, as the travel is far too short and it is much too easy to activate it accidentally when scrolling.

We also believe the left and right mouse buttons provide ever so slightly too much resistance for optimum performance; we seemed to be able to click much faster with our SteelSeries Xai.  This said, the mouse buttons on the Z3RO-G are far from bad and we did get used to them after a few hours of use.

On the left hand side of the mouse there is a thumb alcove which is recessed slightly into the side of the mouse.  This lets you grip it nice and securely during use.  Directly above the alcove we find the browser forward and back buttons.  We found that these were positioned ideally for our hand, letting us use the forward button with the tip of our thumb and the backward button with the joint of our thumb.  Of course, all of the buttons are fully configurable through the included software so you are able to use them for a variety of different functions.

Build quality is exceptional despite the overall light weight of the mouse.  The plastics seem to be of the highest quality and the cable carries a high quality cloth braid that reflects the quality standards set elsewhere in the mouse.  The cable terminates in a gold-plated USB connector.
