It's fast and easy for non-technical people like me who are not used to coding/programming in general or HTML5 technology at all! I can create my own webpages without having any code skills whatsoever - just drag & drop elements from library of ready made pages onto page as if it was Photoshop ;) If you're looking for an online tool where your customers will be able to edit their content themselves this program does exactly what we need.
The only thing i dislike about BPS website builder so far has been some minor glitches which seem pretty fixable by technical support team though there might have already fixed them since they've released new version recently. We use bps product mainly because our clients don't understand how complicated html editing tools work. They prefer simple WYSIWG editor instead but cannot figure out why do other companies make such complex things when simplicity would suffice?
