Ergonomics good! Processing top! But where are the 7 programmable buttons?

I am in search of "my" mouse for some time. Logitech, I have now left behind me. My focus is primarily on good ergonomics and secondarily in many keys. That's why I explicitly wanted to mice with more than 5 programmable buttons and came across the Speedlink Kudos.

The Erognomie is good, the mouse fits comfortably in your hand and the materials on the mouse buttons and the left and right mouse flatter with their "gummy" real surface of the hand. The rest of the surface is not great, but that's perfectly fine.
Ergonomics is reasonably well suited to my rather small hands (18cm length). She is left higher than right, there are slight depressions for thumb and little finger, which as it is written, with a pleasant "rubber" coating are elaborated. However, it is on the right side a bit too high for me. So I have the little finger already angling slightly to prevent it from hanging in the air. This allows the mouse on a permanent komofortabel not operate and the hand clenched.

The keys are to reach up to the front thumb button without any problems, with the would settle with the thumb button on time because they have to use a fingertip grip. The two middle buttons behind the scroll wheel are with a few minutes of familiarization also good to use and differentiate. The wheel has a good, but rather lighter screening, but left and right scrolling is seeeeeeehr stiff. The volume of the key, however, is pleasantly quiet.

The driver offers the usual settings. It is possible to reassign keys, DPI (continuously) adapt, create different profiles, adjust polling rate and define macros. The 5 sections and 4 DPI settings can, however, only by clicking.

My big minus, however, are to be occupied buttons. In the product description which is formulated somewhat misleading. It says, the mouse would have 7 programmable buttons and a 4-way scroll wheel.
I naturally assumed that the two behind the wheel keys would also be programmed, but this is not so, they are given as DPI and profile switcher (or click throughs). The left mouse button can not prove otherwise, so I've only been here a 7-button mouse with a 4-way scroll wheel, with only 4 programmable keys and a programmable 4-way scroll wheel, which is not quite the product description.

I find that very unfortunate because the mouse is otherwise really good. So who gets along with the limited programmability of keys and the fixed DPI and profile switches, for the Speedlink Kudos is quite attractive and he should try it. The ergonomics are always very subjective, me it is on the right is too high, but that may not be a problem for others. However me an assignment for Double would be much more important than DPI or profile change and am therefore disappointed with the wrong product name, for me the mouse is therefore unsuitable.
