Judging the performance of a mouse is base almost purely on subjective opinion. Some gamers like a fast, small and light mouse. Other want to use bigger movements and mice that fill the entire palm, while feeling the weight during movement. The Sharkoon Rush Laser Mouse weights 124g which is toward the heavy end of the spectrum. There are heavier mice out there, with the MX1000 and MX Revolution being some of the heavyweights. The variable DPI setting from 400 to 2000 DPI is great, as it caters to a wide range of users. The maximum of 2000 DPI is quite good. Other gaming mice like the Razer DeathAdder have 1800 DPI, you can read our review

I fired up my favorite game - Half-Life 2 and played through the first few levels. The game requires relatively fast and accurate movement. It may not be as speedy as Counter-Strike, but faster than games like El Matador, Condemned or Far Cry.
Using the different DPI settings is very distinctive. At 400 DPI I had trouble moving around and my gaming surface was not large enough. This setting should be perfect for gamers who want to feel the mouse travel a long distance to achieve the needed movement, but I was simply very slow in the game. 800 DPI felt much better and while it was a bit slower than what I was used to, my gaming style adapted after a few minutes. 1600 DPI felt a bit too sensitive for me, but once again I adjusted intuitively within a short period of time. 2000 DPI was way to much for my taste as the mouse was so sensitive that accurate aiming became impossible in Half-Life 2 and I had to start wasting entire clips of ammo, in the hopes that some bullets would reach the target. While I had problems at this level, there are certainly gamers out there who want their mouse to travel the farther possible distance on the screen, while moving the mouse as little as possible on their gaming surface. This shows the wide spectrum of gamers the Sharkoon Rush mouse addresses.
The buttons of the Sharkoon have very low pressure point, making this great for gamers playing extended periods. The buttons were quite loud, much louder than the MX Revolution or MX518. The scroll wheel on the other hand needs a lot of force to turn, but the grip between finger and wheel is great, alleviating the situation a bit.
The mouse works on all surfaces tested: plastic and cloth pads as well as different kind of table surfaces.
