Summary: Cool little mouse with some very neat features. I got big hands and long fingers so this gaming mouse is most certainly small to me. I use a claw grip and that makes use of the SHIFT button and its abilities diffcult and rather useless. I do have kids that use this system so the mouse is great for them size wise but they don't use any of the extras so that makes this mouse a bit of a bust for my household. I did buy the Kova[+] as a gaming mouse and it works well.
Summary: I bought this mouse last week and is the first gaming mouse I have ever bought. I mainly play FPS games and wanted a mouse with more buttons because I found it annoying having to cycle through weapons using the wheel or number keys. It has two extra buttons on each side and I find 3 out of the 4 very awkward to press when trying to be accurate. The one button I don't find awkward is a "shift" button, which is used to press with another key.
Summary: Yes, the lights are gimmicky but it's a beautiful claw-grip mouse that fits my hand very well (female). You don't have to have your fingers reach the very end of the mouse like you do with the Razer Naga--for the first year or so. The left button is so worn that it's double or triple clicking now, and trying to drag and drop items, or even to highlight text, is getting impossible.
Summary: First if you are thinking of getting this mouse, get this one instead: http://www.amazon.com/Razer-Abyssus-Optical-Gaming-Mouse/dp/B002XLR0JI/ref=sr_1_2?ie=UTF8&qid=1392488918&sr=8-2&keywords=razer+abyssus The Roccat mouse is pretty good and felt great! But it is seriously prone to static electricity. I'll touch it and it will screw itself up and i have to do a hard reset on my computer.
Summary: Short and simple - The Kova + is average at best. I have medium sized hands and find the mouse too small. It's put together nicely and has decent lighting effects, though it still feels light and sort of cheap in my opinion. The most critical fail is the fact you cannot remap the left and right click. Big mistake!
Summary: The mouse has a nice weight, but its shape is not so perfect, the buttons are very sensitive so you end up clicking them without knowing just with the weight of yout fingers. But the material is good. Anyway, almos a perfect mouse.
Summary: Really good mouse for claw grip type of gamers. Nice variety of led colors and 7 buttons. (really there are only 4 but one of them is a shift button) Comfortable for small and big hands alike. Nice dpi speed. The only flaw (and it is a major one), is that there is glue leaking out of the thumb rest pad. And this not only happened to me but a lot of people too. I wipe it out, but it keeps leaking. I have had other "mice" and this is the first one that have done that.
Summary: Good: left click, right click, middle mouse click and scroll wheel work nicely. Lights are fancy. Bad: After a while the side panels ooze glue, and get all over your thumb, not nice. Side buttons are a little tricky to hit, the front side buttons are always a little too far forward. Overall its ok but really you might do better going for a mouse with a better DPI and quality for a few quid more.
