My hubby gave me this cool wifi mouse some time ago. It is really a high tech mouse because it is also a transformer. It can transform from flat thing to a mouse. By the way, the inside tech is created by my hubby’s company. He got it free from his customers. It runs on a wifi technology which means no wire. It uses a USB connected as a receiver. It is also a laser mouse to move the pointer. It is easy to carry with me wherever I go.
