The wide body of the X5 is designed to make you hold the mouse with a claw grip. A pretty ingenious idea to help you with more subtle, precise and faster movements... characteristics needed for FPS gaming (particularly accurate headshots).
Clutchkills specifically states that it took 1 week before getting used to the claw-grip which ultimately improved performance... most reviewers do not normally test for this length of time. So give performance equipment time before passing judgment.
PMW 3360 Sensor For 2000Hz Polling Rate
Some would say that 2000Hz polling rate is overkill and in some respects it is. Ordinarily, you do not notice it when performing bigger movements, however, where you do notice it is with tiny micro-movements that require small adjustment (such as in FPS headshots). This feature enhances the user to make tiny adjustments/corrections quickly when aiming.
All I can say is once getting used to the X5, you will NOT want to go back to your old mouse.
Let's take a look at the components that make up this mouse. As in the review mentioned above, there were some disappointing aspected of this mouse.
Buttons & Clicking Performance
There were no apparent issues with the buttons, but at the same time nothing special either. The click sensation was perfectly acceptable comparing other competing mice, but again, you just got the sense you were expecting a little more.
Wheel & Roll Performance
The wheel was average as well. Perfectly adequate but nothing out of the ordinary.
Rubber Cord & Its Affect
The cord was probably the most disappointing of all. Ironically a part of the mouse that should not be getting in the way of performance actually did!
It is made from standard 'old school' rubber cord that created a bit of resistance when trying to move the mouse around. With larger movements, you did not notice it so much, however, with smaller subtler movements, it does create enough resistance to interfere with your aiming (ironic considering it Minos X5 mouse was designed specifically to be a lethal FPS weapon).
I have to agree with Clutchkills on this one, I too would personally replace the stock rubber USB cord with an aftermarket paracord...
