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: 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: once again i find myself complaining about THIS mouse the kone+ never have i been SO FRUSTRATED AND DISAPPOINTED with a company and a product ive had a number of these kone+ mice now and although they are a great idea every one of them ive had, have had the same problems and really think they should...
Summary: SHORT: Trackingproblems after some weeks (in general and especially after higher acceleration). T(D)CU auto calibration fails no matter which surface i tried out. I guess TCU laser unit is already broken (only after 1-2 weeks of using the mouse).
Summary: I've had two of these now. It's a fantastic mouse and oh so versatile - you can program it to do anything (great for gaming combos and then a quick switch of profile for Photoshop macros... fantastic). So why have I had two? The scroll wheel has a problem. This is well known.
Summary: This is a german company that sell a very expensive mouse so of course you expect perfection right? WRONG! I received my mouse, I was super impressed with it, fantastic mouse, however, like so many others who own this mouse it failed pretty much right away.
