Minie bluetooth mouse. Immediately recognized by my phone (S4). Small footprint for mobile use: great. Has 4 levels of sensitivity, which is handy. However, slight defect on the right mouse button, the button is a bit distorted, sometimes the click of stroke blocks a bit. No system on / off, the mouse turns off by itself after 5 minutes of inactivity, and comes back on a double click, but why not during transportation in a bag she can light alone, reducing battery life.
