Logitech G705 Wireless Gaming Mouse, usb/bluetooth, programmable buttons, RGB lighting. It's hard to find now, as it's apparently out of stock everywhere.
It is missing the original packaging, but includes usb cable, adapter, and usb receiver dongle. Like new, never really used. I plugged it in once and decided I preferred the feel of my other mouse. Nothing wrong with this one, however, it works perfectly. I just don't need two of them.
