Pros
Pro Can help sleep better
Helps provide better sleep for more energy during the day.
Pro Eases eye strain
Decreases color temperature at night, changing the normally fluorescent blue of an LCD monitor to a soft orange. Much easier on the eyes, especially in a low-light environment.
Pro Subtle transition
The transition from daytime to nighttime color modes takes an hour by default and will detect your current timezone, meaning that it will happen in the background at sunset, often without you noticing.
Pro It's reliable, fast and quick
It just works...always. It's fast and quick, which can save you thousands of hours.
Pro Very configurable
You can set all sorts of things from size of database to size of individual clips, types of objects to copy/paste, which hotkeys to use etc.
Pro Scriptable clips
Clips can be used/changed with scripts during copy or paste.
Cons
Con Takes a while to get used to
After installing F.lux, the screen will look a lot more yellow. This takes about a week to fully get used to. You can ease into it by setting the color temps higher than the recommended defaults.
Con Uninstaller removes nothing
After uninstalling removal of almost every file manually from different directories is still necessary since the actual uninstaller only displays "other files still remain".
Con Minimizes after each paste
You have to activate it twice to paste twice.
Con Does not support HDPI displays
On high DPI/resolution displays, the UI is very small. Practically unusable.
Con RTF bug is still present in latest Beta version
You can turn on the option to draw RTF text in the clip list, but it no longer works in Windows 10 Ditto (64bit), and the latest Beta version available today - which claims to have fixed the bug - still has the same bug. It will no longer draw RTF text as-is in the clip list.
Con The UI is very confusing
Con Can't use any shortcut you wish
Anything with spacebar, windows key (that the system also uses) is not possible.
Con Portable version will remove all clipboard record once it is updated to newer version
