This is a Human Ergonomics EV mouse. It is wireless and uses a USB dongle. It has a rechargeable battery. It is new in the box. The boxes do not have a seal and I open them to verify the contents are correct. It comes with the mouse, USB dongle, micro USB cable, and manual. 

I've used one and it works seamlessly on my Mac. No drivers needed, just the USB dongle. The build quality is about average for a sub $100 mouse. Not great, but also not cheap. The buttons have a nice click. The tracking is precise. The DPI changes with a button easily. I think the scroll wheel only scrolls up and down. The "light" switch on the bottom lights up the logo on the side and it changes colors. The ergonomic orientation does feel comfortable and natural. 

I have a few slightly different models of these in other listings. The pictures are my own stock photos. The last two pictures are an opened one from one of those slightly different models. The picture on the box shows the silver panel with bumps and textured finish, but it is smooth and shiny finish on the actual mouse.
