The video tutorials are great. They are intuitive and every one covers a functionality from the beginning to the end explaining the workflow and giving a fair amount of fundamental background information. After watching them you should be able to use the software without any trouble. 

The interface is second nature to me after having assigned hotkeys to the functions that I use more frequently. The software works very well with a tablet ... I use a Wacom Intuos for painting. 

I like it for what it is ... a streamlined texture and morphing tool.
