"Ordered and received the product within 5 days. The Design is Awesome and has USB Dongle Holder. It requires 2 AAA Batteries. It's working great, haven't faced any issue on setup or daily use.
The Battery life is 3 months (Specified in the pack cover) which I yet to test. Bought N50 Black Mouse which needs single AAA Battery and has 1 Year Life (Guaranteed). Thought this mouse also has that much Battery life.
If you are looking for more battery life and size of mouse is not big concern then Go for N50 Black. If you looking for small, sleek mouse and battery life is not a concern then this mouse is Perfect."
