Hey Paddy!
I've just started playing on it, and I'm someone who's never played a guitar in his life.
Basically its a good tool for practice, however you will get the most out of it if you have a friend who is a good player, because otherwise it will teach you a lot of bad habits.
Basically its perfect for someone who knows basic technique and needs something more fun to get them to regularly have a go practicing.
Hope that helps!
