the theme is really easy to use, IF you are happy with the standard settings.
What I absolutly do not like on that theme is the fact that you can not anything with the WP UI, you have edit the styles.css for every piece you want to change.
of course there prepare snippets, but for a newbie it is always the walk on the thin red line between heart attack and jackpot win.
having a fully CUSTOMISABLE (I guess that is where the name is coming from - customise, but you can not customise things easily) UI like at the "Atahualpa" or "Suffusion" themes would be make this theme totally awesome.
so... it is "only" a very good looking, but not really beginner friendly theme.
