Comanro 2.4g Laser Wired Vertical Ergonomic Mouse 6 Button 500/1000/2000/3500 DPI for PC-Small Size (Wireless)

Returned it. Mouse is a good ergonomic shape. The mouse worked initially when wired, never worked as wireless, then ceased to work at all. I emailed the contact provided on the mouse-maker's website and never heard back.
