I use for graphics packages. I have tried many expensive mice before in combination with various mouse pads. Perhaps this one is not the most convenient, but I hope for the quality of the buttons. Because tired of soldering them or constantly spending money on new mice. It is felt that both the mouse itself and the software were seriously thought about. But it is also clear that it turned out to be a kind of compromise in an effort to please everyone and hit the performance characteristics on paper. I got a copy, newer, which is being reflashed. There are those who can't do it. Software inspires, no, no, not like that: the software is very, very impressive. You can choose whether the mouse will use the profile from the internal memory, or will choose according to the program currently running. Auto-detection is very correct. Each profile can have up to 3 subprofiles. And each subprofile can have more options with pressing G-Shift. For each profile, you can choose how many levels of sensor sensitivity will be: from 2 to 4 for memory from the mouse itself, and up to 5 with software profiles. Which of these levels will be enabled by default, and which one when you press Shift DPI. Bonus: the dpi change is displayed on the G13 screen. You can adjust the backlight color and flashing frequency, or set the backlight cycle to change. With continuous operation of the backlight, the side keys heat up quite significantly: it can be pleasant in the cold, or interfere in the heat,-) The macros themselves are easily dragged by the cursor to the desired button, as in G13 (with a software profile), when using the memory from the mouse itself , for some reason - no. Unlike some other mice, vertical-horizontal sliding is equally smooth. I am very demanding and sensitive to this moment. Mat Razer Speed Edition. I also set up and get used to the grip, remember the assigned commands. It is very convenient to scale in graphics packages, move along the time line from marker to marker. Tactile pressing is very pleasant. And the correct sound of operation. I really hope for the declared resource of the buttons.
