Shades is not the only application which gives us extra control over the brightness of our Mac, but it is true that of all the ones I have tried it is the one that behaves best and the most complete of all.
It works in the same way as the rest, artificially darkening the screen (come on, it doesn't use the screen hardware), thus achieving extra control over the brightness that is great for staying overnight on the Mac without bursting. both eyes.
Allows you to configure keyboard shortcuts for almost all options, it is installed in the Menubar with support for multiple monitors, it works wonderfully and it is free. Does anyone give more?

This application is useless, when you open it automatically it lowers the brightness, then you raise it to 100% from the Shades panel and it is exactly the same as it was with the Mac controls at 100%, it does not matter, it remains the same, there is no profit, I do not recommend it.
