Summary: This mouse is a great gaming mouse, high quality, and with a steelseries mouse pad is a great buy. My only complaint is the drivers take a REALLY long time to apply changes in windows 8.1. I've tried every compatibility setting possible, but no change. If you change settings and hit apply, it literally takes a minute to apply the changes. I don't change the settings often so it's not a big deal, but I wish they'd update it.
Summary: First, I'd like to say that Roccat products are amazing, some are pricey as if they were Razer. This was exactly the price I was looking for. - I really like the way it looks and it is just very flashy. There 4 lights, and it glows 7 different colors or 1 if you set it that way. There are 2 side buttons on each side and like any new mouse takes some time to get use it. Let me tell you, I don't know if it's just me, but every time I use this mouse, it gets all dusty.
Summary: Bought this to try out because it was on sale. I am using for secondary computer. Better than any standard mouse I've used but not quite the right fit for gaming for my hand (-1 Star for that).
Pros: Got it on sale for 30$. More comfortable and better quality than a standard mouse.
Cons: Placement of thumb buttons. While easy to press, they just don't feel right for my hands.
Summary: Good software, very customizable. I like the size and shape. Buttons work well. Feels like quality mouse. Main negative for me is the lift off distance, it's a little higher than I'd like, but I'm picky about that... Would not be an issue for most people at all.
Summary: I think the ROCCAT Kova[+] doesn't have enough recognition as it deserves. The bold design and customizable glowing lights look great in comparison to many other mice out there. The mouse also comes with a CD that allows you to program and set up different profiles for various games or programs that you will be using. I personally use this very often and find it very helpful when transitioning from gaming to work.
Summary: The shape fits my mouse holding preference (Claw Grip) and the texture feels nice. The non-slip side surfaces are indeed non-slip, and the long mouse mouse buttons provide a good range of where you grip the mouse. My only issues are that when I lift the mouse, it seems to open slightly, as if there may be a loose screw keeping it together, and the Macro portion of the driver.
