The interface of this tool was easy for me (a non-developer) because it's very intuitive! I've been able build many different types landing/funnelled sites with ease - all without writing any code myself!! It does take some time getting used too but once you do there isn't anything better out their at present so don;t be put off by initial learning curve as its well worth your while when fully implemented.
Have also found great support from team behind product which has made life much easier compared other platforms we tried previously etc:-).
