What is totally unacceptable but for me that I have to change the battery every 2-3 weeks (with daily use of 4-5 hours). For me it is the first wireless mouse, so I have no experience. However, my colleague used the office for 6 months a cordless mouse with still the first battery (also 1 AA).

Yesterday, the mouse has ceased operations. The image sensor lights, but otherwise no reaction. Meanwhile, the anger on the part outweighs quite a bit. I will now have access to another manufacturer.
