The platform is very intuitive, we've been able use this system for years without any issues at all! It's not as flexible when you need more advanced functionality like custom fields or geotargeting but I would say they are working hard to improve their offering with new features every month - so get in touch if interested because these guys have got some great people doing awesome work over there now!! We can't go wrong here- its an incredibly powerful solution which has helped us grow our client base quickly by providing them access via email directly from within Facebook ads (which means higher click through rates).
