The wretched wheel - metal with notches like a file, has sharp edges, from which at first it was not comfortable to use it and the finger even hurt. The scroll was tight and even the notches did not help, the finger just slid over them, because. metal, not rubber. Then, apparently, the wheel developed and after 2 weeks I got used to it.
The wheel is shaped like a cone rather than a cylinder, as seen from the top and front views.
And I still feel the shape of the cone, because the finger on the LMB touches the sharp left end of the wheel, which is unpleasant. Made apparently under the 1-3-1 grip, when the middle finger is always on the wheel, but with the 1-2-2 grip, the index finger has to be thrown over this ledge, and scrolling by the end is not comfortable.
Also, the wheel has slopes to the sides, which, coupled with its shape, is not entirely logical, because. when you click on the scroll, the finger does not press strictly vertically, but at an angle, and can lead to pressing sideways. But so far there have been no false positives.
There is built-in memory for one profile, and this is a plus, but everything spoils that not all settings are stored in memory, and for the sake of a couple of chips you have to use synapse. My previous mouse Razer Mamba stored any settings and macros.
Synapse does not show percentage charge on Pro Click. Yes, only for Pro Click, for other mice with a battery it shows. The percentage of charge can be viewed in the windows settings in the device section, but only when connected via bluetooth.
