Very Buggy, Unreliable Plugin

I used this plugin to build a school lunch ordering system and it seemed to do the job okay for the most part, but with every update there are a lot of bugs and quirks that cause the forms to not function properly, lose entries, not process payments, and other unforeseen problems. These constant hang-ups made my client and I look very unprofessional to our customers and lose some of our business – and some kids were left without a lunch! We switched to Gravity Forms and have had no problems so far. If you are using this plugin for accepting payments or any serious business application I would stay away.
