I did not recognize the mouse in about a week. Even if you change the batteries, it is no good and inquiries to the manufacturers are troublesome, so purchasing items of comparable price with another mail order, it is a product that does not seem to be Logitele one month but it works.
It is used for NEC's Lavie 2010 Vista. The body is somewhat smaller than the attached standard mouse and the operability is very excellent. I also like the design because coloring was the same as the main body.
Slightly big, point movement, unevenness in movement and no sharpness. After about a month, I did not recognize the mouse. Even changing batteries did not solve it even if they contacted the manufacturer, and the manufacturer's reply also disappeared. After all, it was useless shorts.
