This mouse is after many attempts, the best solution for me. The size of the mouse is absolutely perfect (I 1.84 / hand Length about 18 to 19 cm). The wireless connection (to about 60 cm) holds and has not let up. The ergonomics is really very pleasant. The key click is also very light, which is very important in every day 8 hours use. The mouse wheel is also working well. On 09/16/2014 I bought this mouse and today (05.04.2015) after daily 8-hour use of a used battery with 1500mAh Duracell was empty. Since you can not complain yet. I would buy this mouse repeatedly.
