I4U: Logitech VX Nano Review
 

If you are a fan of the VX Revolution, you will probably like the VX Nano even
more. The tiny USB receiver is the highlight of the Nano and the free wheel scroll
is great as well.
The Logitech VX Nano is a laser mouse with 800 dpi sensitivity and it is able to
track accurately on any surface but clear glass and mirrored finishes. The most
important feature of the Logitech VX Nano is the tiny USB Nano receiver that is a
mere fraction of the size of typical notebook mouse wireless receivers.
