+ The materials are pleasant to grip, whether the plastic to the touch "velvet" (pretty good), rubber grip under the thumb or smooth plastic under the fingers of clicks.
+ The weight and size of the mouse are nice enough, it fits nicely in my hand, and is neither too heavy nor too slight (it has a solid feel).
+/- It is indicated that the mouse has 6 buttons, careful though, the 6th serves as a priori change the DPI. One would have liked the side button on the wheel, but at this price, it is understandable that there is none.
+ The wheel is notched and works well.
- As mentioned in another review, the location for the AA battery is a bit narrow, it's not really a problem to put it, but to remove it, it will open the door and shake the mouse over the the other hand to dislodge the battery. That said, the battery change is not supposed to happen too often.
+ The nano receiver is small and connection to a PC with Linux poses no worries, a location under the mouse allows it to be built which is convenient (for against, I could not test whether it sustainably securely holds).
+/- The sleep is a good idea, but lack of documentation, I had to realize that on wakeup had to push a button (I was used to a mouse that had a way of "semi-sleep" who awoke to movements). Once we know it works well, it is less immediate, but it allows the mouse is not erroneously operated for systems that have two mice (wireless serving on the coffee table to control the videos for example).
+ The selection of IPR can be practical, personally I use the lowest setting for more accuracy.
Finally for the price the quality is really to go, and I can only advise his purchase!
