Summary: Wow, the surface is slippery. The weight is not light regarding to its size. And also the most complex driver settings. The default lift distance is ridiculously long, which impacts the game significantly. I don't see any point of this mouse.
Summary: This mouse comes with the typical driver, except after a little use when you are least expecting it ALL OF A SUDDEN YOU GET A VERY LOUD VOICE FROM YOUR SPEAKERS, "YOU HAVE WON A TROPHY" and it periodically says it randomly from that point on.
Summary: I got this mouse and it worked great for about 4 months. Then all of a side panel fell off. It was glued on! I can't believe they just used glue to hold the panel on, I'm not a manufacture but I figure they would use something more high tech then glue.
Summary: I bought this mouse to replace my Corsair M-65. I was not impressed at all with this product. It feels very cheap made, thought I was going to break it installing the weights. The software is just horrible. It was causing screen freezes constantly. The mouse pointer was ghosting on the screen.
Summary: After about 3 months of use, the scroll wheel sensor broke. When I investigated the problem, it turns out that the "scroll wheel glitch" is an such a common problem with this mouse that it has its own name and multiple help guides/videos to try and repair the issue.
Summary: I can never fault Amazon on any items iv'e ordered before. but this technical abomination is possibly THE worst mouse on earth. Having used many a gaming mouse this was my biggest faux pas. The scroll wheel went mad after a week then went totally off the rails at week 3.
Summary: This mouse gets a scroll wheel bug. Always. You can't escape it, then when the wheel grinds down the dust that slipped inside it finally starts to work again, but today, after waking the computer up, the lights and button configurations are not my own, I go into the mouse's files, my .cfg is gone.
Summary: What can I say, I read the reviews but still bought the Kone+ in June. I have been very happy with this mouse up until yesterday, robust and well proportioned (for my huge hands) and I liked the layout of the additional buttons. However three months later and the tracking has completely packed up.
