Good idea - insufficient implementation.

Hello, I am looking for a mouse, where you can put your hand relaxes it and use the buttons well. Unfortunately, there does not seem to be such a thing on the market. All mice appear to be designed for the small hands of the Asians. Ball documents I find disturbing, because the freedom of movement is then very limited.
With this Microsoft Mouse now everything should be better.
The basic concept is not bad, but unfortunately has not been thought through:
1. One must be very focused on the right hand position, the shape of a not force the right attitude,
2. The rotary wheel is too close to the center, resulting in that the middle finger can bend too far needs to operate the wheel can,
3. No meaningful standby function. The mouse is essentially always on, you have to turn it off to conserve batteries cumbersome. Why is not it possible that such a device switches off after about 15 minutes and even when the first keystroke activates again?
Conclusion: The mouse goes back!
Should there eventually a cable version, I try again.
Regards
