The mice arrived in a cardboard box with instructions in English only. Once the batteries in place (delivered with 2 LR03 batteries), big moment of doubt since it does not see the infrared as my previous mouse. So I changed the batteries and spare before I realized that it says "invisible Optical". After this uncomfortable time, I try and research the nano receiver. But nothing. A quick glance on the leaflet does not help me. I turned the beast which I had not yet recovered the battery cover and there, eureka, I see the mini nano receiver housed next to the battery like a fuse! I retrieve the plugs into the USB port on my computer and everything works immediately. Clicking the DPI button still allows you to see the infra red briefly. This is also indicated that the mouse will flash when the batteries reach the minimum level. This lack of visibility of the IR may participate in energy savings claimed by the manufacturer. Thus, he stressed that the mouse automatically switches to economy as soon as you do not use it. However, if you do not use it for a long time, the conventional on / off button is kept. To see the long term if the batteries really take longer.
What makes the originality of this mouse is primarily its original design and its morphology. It is indeed scheduled to host the 5 fingers. In addition, you can adjust the thumb rest at 3 different heights with a button under the mouse. Not having huge hands, I prefer not to leave the thumb rest or while on position 1. It's confusing at first but soon enough we made it all the plastic on the sides is comfortable.
Finally, with the supplied CD (fast installation), you can program all buttons (you can, for example, program the two thumb buttons to increase and decrease the volume or to go forward or backward in navigation). Clicking the middle mouse button also allows to bring the mouse cursor in the center of the screen, which sometimes proves handy. It is also, in a more conventional manner, set the speed of movement or double-clicks.
In summary, this ergonomic mouse is really excellent and we adopt it very quickly, provided they handed (left-handed, go your way)! A return to the old mouse then seems more than strange. A counselor therefore to all those looking for a different experience with their mouse.
