The sensor here is pm325, according to the representative of the company Aula. The materials are quite good. The main thing is that the tactile feeling from them is quite pleasant. And I think that for summer, it will be very good, your palm will not sweat so much. The surface is smooth, as in the photo of the manufacturer. That's why I took it because something tells me that for summer, it is this material and a white mouse, it will so be allocated sweat. And not wrong! Side panels on magnets. Keeps well. And at the same time, everything is removed very easily, which is good. Played in Destiny 2, Warframe, Battlefield 4 , 1 and the Division 2. It wasn't bad. On the keys! Shooting and aiming keys. If you are used to the fact that you need to feel the work of the sweater when you press, then alas, you will have to take it off. For here, instant operation when pressed, and only then, click. And for me, this is just a huge plus. Side buttons are pressed well. To the panel with nine buttons, you need to get used to it.
