I had bought this mouse seven years ago. Even now the mouse works perfectly without any defects. In the first use, I felt that the optical mouse is a bit large. But after some days I realised that it is so handy than the small mouses. The wire is usb. There for it can be connected to any mordern computers. I used to connect the mouse to mobile phone, computer, laptop etc. The muse is very nice to use. Even without the mouse pad the instrument works so well.
Good things about it are : Long life, correct size, optical laser, usb connection end.
I suggest you to buy this item.
