Have bought the V450 Nano Cordless Laser Mouse for my HP notebook and am totally satisfied with the product. For me personally the mini USB receiver has fallen. One can without problems always be stuck in the USB port, even if you pack the notebook in his pocket. The mouse responds very reliably and the batteries are making loud hold almost a year, since the mouse is in an extra power-saving mode when they are not moved for about one minute. If you want to switch off completely the mouse, which is also a separate "Power" button on the bottom of the mouse.
For the money you can not complain really about performance! ..
