Review on Mouse Logitech M100, dark gray by Mateusz Grzesiak  (M ᠌

Cheap plastic causes the fingers to perspire, causing the surface to quickly become dirty. As a result, the keys occasionally stick to the fingers a little bit and make an unpleasant rattling sound when pressed; I particularly notice this on the left key. You have to exert effort to feel control over the mouse since it feels as like it is being lead by the wire because the wire is hard and the mouse itself is light, which is uncomfortable. When pressed, the scroll may readily scroll a few divisions and scrolls with a faint but unpleasant rattling sound. Although it seems to me that the size of my palm is about average, the manufacturer clearly misjudged the size of the mouse, and I certainly do not advise this mouse for those who have huge paws. Although it may just be a cheap LED in this case, it feels like there is not enough frequency of reports even though the laser is still better, more accurate, and somehow more responsive. But it seems like everything is definitely not as clear now that the laser has faded. The case's form is OK, but ergonomics definitely aren't its strong suit; extended use wears down the brush.
