The best thing for macros.
I have had it for 4 months. Personally, I don't use it for streaming, but for video editing, animation, programming, 3D modeling, and of course for various shortcuts (links, folders, programs...).
As for its construction, it is plastic but it is sturdy and fine. No problem.
The brightness of the screens is adjusted through the software.
Its software is flawless and it is quite easy to set up.
It has an option to create profiles that automatically open when you are in a specific program. For example, one can set it to display a specific profile when opening Chrome.
Everything works very well. I have never experienced crashes or any issues.
The macros are literally unlimited. You can create profiles within profiles within profiles, call them from anywhere, and have unlimited possibilities.
If you like automation, then it will probably be an interesting and useful tool for you. Although in my opinion it is not necessary (I can do my work without it), it will definitely save you time if you sit down and configure it to your liking.
Personally, I combine it with various AutoHotkey scripts, so for those of you who are familiar with it, know that it works perfectly, and of course, with this combination, you have even more possibilities.
Finally, a pro tip is not to use folders, but profiles. You create each profile once and call it from wherever you want, while with folders, you have to create them again and again if you call them from different points.
