I'll go directly to the shortcoming mentioned in the title: The left mouse button was after about 2 1/2 months NEN any mistake - they did not click easily. But I did not want to send them back, so I have unceremoniously opened, and looked to see what was - was nothing ... When I screwed together again, they went back (ago is now almost exactly 2 months, I have the mouse for about 4 1/2 months) properly. Well ... let's see how long ^^ Now to the actual review: This mouse is an all-rounder that makes my life on the PC is many times easier to play brilliantly, and I'm just completely satisfied with her on all counts! The speed can be adjusted perfectly thanks to Logitech SetPoint, there is a mouse of internal memory that the mouse internal functions (which you can really completely customize in any way to your own needs) stores that you can really adapt in every way completely to your own needs, the one with the "key programming" is not a problem, you just assigned a certain key to certain functions, etc ... simply awesome! For example, the middle button, which is left on the mouse side (the thumb) - I can not do anything with the original function, now I have just a Play / Pause button made of it in order to stop the music at any time, without the to press the pause button or the spacebar (When VLC player for example). The mouse speed is ... fantastically set, wenns an annoying having to move your hand always eternally much back and forth, you can simply press two or three times on the + button, but you will not even ausversehn it because it far enough is forward, and thus achieve a little heavier Accordingly, the - button when the mouse speed will be slower if you even need a very precise, slower mouse (although the mouse is very accurate even at very fast speeds ^^) It should not be forgotten that they only wonderful in the hand is easy and looks really nice (I think).
Again as a list so as not to deny the read fouling the advantages of the mouse):
Positives: + Is beautiful in the hand + Weights - they bring me hardly anything, but with weights, the mouse feels even better to + Beautiful mouse (subjectively) + Speed beautifully adaptable + Very visible, what speed is currently selected (by LEDs) + Tastenprogrammerung very easy + Very good individually adjustable + Software to set the mouse is included, so no need to runterlgeladen + Keys all easily accessible + Cable is long enough, and not as rigid as the material looks at first
Neutral: - Mouse wheel wobbles a little back and forth, but almost did not bother Wen really bad, the mouse should not pick
Negatives: - Left mouse button might not work, reason unknown times, by mouse or return screw again to fix - Hmmm ... that I knew nothing further
Would this major shortcoming at two and a half months have not been (which some would certainly have led to a 2-star rating), there would be from me uneingeschräkt 5 Stars! And of course there's also a full purchase recommendation! A really nice little mouse, you can buy here;)
