-The Mouse good tack of the materials here. The rubberized surface feels great in your hand.
-The Keys are easily accessible and have a good pressure point beyond are 7 in number plus 5-way scroll wheel (with included the wheel button) available.
-With The Easy-Shift function allows the key number again expand by 11 keys, just awesome!
-The Mouse driver is seeeeehr extensive. It can be all the buttons occupy any, create your own macros, create different profiles, set Mouse-lift distance, adjust DPI, set USB sample rate, adjust colors ...
Adjust colors? It can be defined with 4 integrated LEDs different color profiles. I thought at first gimmick that nobody needs, but if you have got time created mouse profiles with different key assignments, you only recognize the value of this function. And, if they were not there, I do not care if it were.
Neutral:
-The "Audio Feedback" feature, which is a different in different volumes settings feeds back a matter of taste. I've been using the color-Feedback (does not go for the DPI setting) enough feedback, so I have switched off the audio function. Maybe this is interesting for gamers.
-Also The additional weights are rather unnecessary for me, but again, this can rather be of interest to players.
But there are also negative:
-The Wheel is somewhat too sluggish for my taste.
-As I have set up the profile, the mouse has "hung" and I could not switch with the defined key profiles. NEM reboot everything went back and since then I have now set up the profile, it also did not come forward again.
-The Ingenious Easy shift function can be set only on the unfortunately two thumb buttons. Back and forth for me, however, the more important features that I like to have the thumb buttons. I do not totally understand why you can not put on one of the central keys.
-The Processing of 85 not worthy. Depending on where you look at the mouse, the LEDs appear through by far too large gaps. Including the cover falls to the bottom, which is not yet disappeared, but already seeeeehr strong rattles. Am now gone so far that I would rather decreased.
-My Biggest gripe however is the ergonomics of the mouse. At first I thought, even though the mouse is very large, it is relatively good in the hand and I can reach all the buttons. I was glad to have finally found time a mouse for my rather smaller hands (18cm). After a week of work with it, I realize how often cramped my hand and I have to take back to hand my old MX Revolution (despite their annoying double-fault). In principle, the ergonomics is not so bad, the thumb has a small hollow in which it locates, the mouse is left higher than right and it is in your hand, that the wrist is relieved on the table. But what caused my cramped hand, is the right edge of the mouse. It is much too high, so that the little finger is excessively bent. Thus the little finger is not charged, you have to hang it on the table and because the edge is so high, it becomes so strong angled such that the hand cramped after a few hours. Worse is additionally if you anwinkelt to scroll around the middle finger, so you spread the fingers but very unnatural and cramped very quickly. If an attempt is not the little finger so strong to bend, you have to maintain, resulting in even faster to a cramped hand him in the air. If the mouse on the right side 5mm to 1cm deep, the problem would probably not occur. Unfortunately, that is not so obvious at product photos at Amazon, which is so not only in this mouse, because the right is relatively rare displayed. Since this is the 3 mouse already, in the right side causes problems to me, such product photos would be a good preliminary decision support and I would have the mice not always return.
That leaves a, subjective, ambiguous impression mouse. I think they respect. Of materials and functionality super and really well thought out. In some eyes probably too exaggerated crammed with features and gimmicks, but better too much than too little. The build quality I could even get over, because it gives a sophisticated look for the materials, but the ergonomics makes for me unfortunately difficult usable.
Edit 01.12.2013:
The driver now has again messed up the profiles and I can not permanently change them again, the mouse ends up repeatedly in the default profile, without my Switch manually. I thought that would be an error which has occurred during the creation of profiles, but apparently the driver has the quirks more often. But I prefer degrees again a ZIP code, it did not work MMN.
