I needed a small change to this extension so I emailed the authors to ask if it was possible. Within 5 minutes I had an email requesting clarification of my needs. I supplied the info and when I returned to my site in the morning the change was complete!!!! I've dealt with many developers over the years and by far, this was the fastest resolution to a feature request I have ever had. I would not hesitate to use this extension or this developer again!!!! Many thanks for a great job!!
