Logitech MX Duo Cordless Elite Wireless Keyboard and MX700 Mouse with receiver

Description

Logitech Cordless MX Duo set with the Logitech Cordless MX Elite Keyboard and the wireless MX700 mouse.
The cordless receiver works BUT the charging circuit does not. The mouse works just fine when you put batteries in it, and rechargeable batteries work, but you have to charge them externally. The wireless receiver DOES NOT need the power supply to work as a receiver if you're using it with USB, as it can be powered through USB then.
The rubbery coating on the mouse is sticky, which is just something that happens to those coatings over time, you can usually clean it up with isopropyl alchohol. The keyboard works fine also, just a bit dusty. No issue with battery corrosion in either device.
