The product is aesthetically pleasing and easy to use. However, it might be somewhat undersized for individuals of larger stature. The seller's prompt shipping is appreciated.

The mouse works perfectly. Upon connecting, the computer recognized it as two separate mice and allows for simultaneous connections. One connection uses Bluetooth 3, the other uses Bluetooth 4. A button on the bottom lets you switch between which computer to use. Pressing this button illuminates a green LED to indicate the selected connection. The first connection is furthest forward. Pressing the button again activates the second connection, and so on. The mouse also includes a small USB connector, enabling the connection to a third and fourth computer if needed. I also use one keyboard with two computers. Delivery took 4 days in China, including the flight. Customs clearance in my country took a week. However, the mouse arrived at my home within 10 days. Great! Happy :)

I appreciate the quick delivery. The mouse is functioning correctly.
