This is a Human Ergonomics EV mouse. It is wireless and uses a USB dongle. It has a rechargeable battery. It is new in a sealed box. 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. Notgreat, but also not cheap. The buttons have a nice click. The tracking is precise. The DPI changes with a button easily. I think thescrollwheel only scrolls up and down. The "light" switch on the bottom lights up the logo on the side and it changescolors. The ergonomic orientation does feel comfortable and natural.

I have a few slightly different models of these in other listings. The pictures are my ownstock photos. The first three pictures are of one from an opened box. The last picture is from a slightly different model, but shows how it will be packaged.
