The two main buttons are extremely quiet in fact. Not silent, but the little noise goes under in a normal background noise. My click-ridden by me roommates are certainly overjoyed now nothing mitzubekommen when I zocke. All other keys are normal Micro switch, you thus also can perceive normal. So the mouse is no Flüstermaus per se. Scratch me not because I seldom use other mouse buttons except the wheel and the two main keys.
The mouse is with me well in hand. The rubberized thumb side helps to guide the mouse well. The transitions from the lid to the bottom of the mouse are quite sharp in my device. Not so that one off cuts, but you do not notice a distinct ridge. Detracts now my positive judgment, but it should be mentioned.
The mouse has two different sensitivity levels: 800 and 1600 dpi. Eight hundred is really too support and thousand six hundred already too quick. I had a little used to it and was wondering how to use mice with well over 2400 dpi? If you had been on the road with a simple optical mouse, or even with a mechanical, then you will be surprised at first. But with a bit of tweaking in the mouse settings to fit. Now when I am sitting at other computers, then have their mice shit slowly;)
All in all a Great Mouse! I enjoy it and my environment is happy if the rest gamble at. Only I'm curious on how long it withstand the switch. The old Logitech was over 5 years thousands of clicks by ..
[UPDATE 14/12/2013]
I regret to runterschrauben on 2 pts evaluation. This is due to a defect. From one day to the next was no response from the mouse more. Although Hama sent me directly and free of charge a replacement mouse, but their processing was so bad that the right mouse button triggered already at a touch. A new call in Hama, and I should get another mouse. That was 8 weeks before! I now have even helped me and just played from 2 mach 1, as I combined the intact bottom of mouse 2 with the upper shell of mouse 1. Now she is running again as intended, but I'm a little disappointed.
Only 2 points because the mouse is really quiet. The rest are but from a rather sad picture.
