Manufacturer description
The Rii RM200 is a compact 2.4GHz wireless mouse built for people who want RGB lighting and a rechargeable battery without paying gaming-mouse prices.

Frequently Asked Questions
Does the Rii RM200 need batteries?
No. It has a built-in rechargeable lithium battery that you top up over cable, so there are no AA or AAA cells to replace.
What DPI settings does it support?
Three levels: 800, 1200, and 1600 DPI, switchable on the mouse so you can slow the cursor for detail work or speed it up for a large monitor.
Will it work with my Mac?
Rii lists compatibility with Mac OS X 10.4 and later, plus Windows XP, Vista, 7, 8, and 10. It is plug and play through the USB nano receiver with no drivers to install.
Can I choose the RGB color?
Not according to the listed specs. The backlight cycles randomly through 7 colors while the mouse is in use rather than holding a color you select.
Is it good enough for gaming?
It is marketed as a gaming mouse for the lighting, but the 1600 DPI maximum and 2.4GHz wireless connection make it better suited to casual play, laptop use, and everyday work than to competitive shooters.
