This is the best ever Mouse I've ever had. It lies perfectly in the hand and can also be easily operated. The battery lasts quite a long time and can also be downloaded quite briskly again. We have in the meantime all the "old mice" to replace this. Even our friends found the mouse so good that you bought these. Although it is not very cheap, but also not the most expensive and besides ... who buys the same something good, more joy has it. 5-star and definitely Emfpehlenswert.
