The customer service has been amazing, they have always responded quickly to any issue or question I've had.
They are very knowledgeable about their products which makes it easy when you need help with your form/plugin integration! Their support team also does an excellent job of keeping me up-to date as changes happen in WordPress itself (and sometimes even adding features that we didn't know existed!). There's nothing really bad at this point from my perspective - everything works well enough but there isn't anything out of place either :) If all goes according to plan our next step will be implementing some additional integrations into Gravity forms so more people can use them without having to go through us directly! We're using gravityforms primarily due to its ease of setup compared to other options available like Formstack etc., however because of how flexible and powerful Gravities' plugins allow users who aren't familiar wtih coding / programming languages such as PHP & MySQL these types of things.
