The ProtoArc EM06 Wireless Trackball is a great input peripheral with 7 customizable buttons, but it doesn't need any software or drivers installed! It's like I/O magic. Here's my detailed demo and review: www.youtube.com/watch?v=ycCp... #mouse #trackball #peripherals #protoArc

Using this EC200 for few weeks. Really comfortable and has tons of adjustment. Great value for money. #ProtoArc
