Implement to existing Joomla Website? How easy?

Hello,

I have a client who runs this Joomla website: bit.ly/mQxWPT

Based on what your extension promises - are you telling me that all I need to do is install this extension and I have a mobile site based on the content from the main website?

I am not a Joomla man, come from a strong WordPress background..

I also need to know:

How easy is it use?
How easy is this to style? CSS, images etc
Is it user friendly?

in short:

install
set component settings for each phone
go to module manager, set the menu for each phone (can also set all to desktop menu)

Thanks Spubs,

That's all fine and dandy, but I have looked at this site on my iOS device and it seems a little basic in terms of styling? Also not everything is a flush as it could be, for instance I viewed this post on my phone and the text was squeezed down to a very narrow column but still had a large font size...

How easy is this to customize in terms of styling? I need this to reflect the image of the main website, not a 'fake' iPhone app.
