A:AnswerHi, The M330 does not need a mousepad as it uses a High Precision Optical Tracking. It will not track on glass. If your desk has a glass surface you may need to use a mouse pad then.
A:AnswerHello Bobbin, You most certainly can use the M330 Silent Plus Wireless Mouse with the K800 Illuminated Wireless Keyboard effectively. I suggest using Logitech's Options software which will help both mouse and keyboard to run optimally and let you customize buttons and scrolling behavior. Here's a link to for you to download it to your computer: https://support.logi.com/hc/en-us/articles/360024842673--Downloads-M330-SILENT-PLUS. Best Regards.
A:AnswerHello Art! The M330 Silent Plus Wireless Mouse comes with a Nano receiver yes, but note that it is not Unifying, just a regular Nano receiver. It should be stores under the mouse, and you can find it by simply by opening up the battery cover.
