We love Fast Field Forms.
Fast Field Forms has been a great addition to our company. We use it on a daily basis, and are getting more and more form creation requests from users in the field. The customer service team is kind and responsive also. It is also nice to see that the developers have been continuing to make improvements to the system since our companies onboarding. There are still a few things missing, such as API integration to the forms from outside sources. I am however confident that they will continue to work and add more content in the future. Overall, great product and great people developing/supporting it.
