Bluestreak Crystals review for Hulk Contact Form Builder

I have been using this app for a while, but I can't say I am happy. They keep having a problem sending the information submitted by my customers via the forms to my email account, so if your forms are used for time critical or important business requests, i would think twice about using this solution. Their developer is never really around, probably in bed. I am looking for a more reliable solution. Annoyed, frustrated, yes all of the above.
