The best part of this tool was its ability for me as an individual developer, who wanted my own customisation options in terms of colours & font size etc., without having any coding knowledge at all! It took some time getting used with it but once you do get into using head room js there are tons more features which can be added easily by just writing code (which I did). There were few bugs when initially launching website or loading page from mobile devices such as iPhone/Android phones where sometimes images would load up very slowly even though they should have been loaded quickly if not instantly upon opening them!! But overall good experience so far :) Would definitely recommend anyone looking out something like these kind tools - especially those related towards web development / design field.
