I like it, it has monitor profiles, a little clunky. However,it misses a clock on the smart task bar, start button and application shortcuts on a taskbar.  Some of the things I really like about Displayfusion are missing, but it has the ability to save the position of desktop icons - which I thing is critical, monitor profiles, and turning monitors off.

Similar to Ultramon, but much more expensive

This is probably the best, but it lacks some important features.
It misses..

1. Being able to save the position of icons
2. Have monitor profiles 
3. Able to disconnect monitors 
4. Can't minimise the desktop on one monitor only

I like

1. Start button on each monitor
2. Able to fix applications on additional taskbars
3. Resize and move to left in the same monitor, resize and move to right in the same monitor
4. Additional task bars have their icons and the main taskbar all icons
5. Additional task bars have a clock
