Since I needed a mouse for a further distance (4m) and uneven surface (bed, sofa) I've tested in the last few weeks several mice from different manufacturers, to 2.4 GHz and 27 MHz base. For all mice I had either the problem is that they only had a short range and thus "have" for 3M gave no function or the Resolution (DPI) was no longer sufficient and thereby incurred massive problems on uneven surfaces. All this I had to give back.
But this LOGITECH M305 can to Entferung and sample rate received relative smooth 1+ from me !!!! You work for me on the most uneven surfaces and even at 5m distance (greater my living room is not * g *) Can this mouse only recommend !!!
