I always have a worry when buying a commercial extension for Joomla that, without fully testing it in its intended installation, I may be wasting money. No regrets this time!
The extension performs our site's specific ticket sale requirements perfectly and simply.
There were several issues I had with proper configurations, etc. Robert was always very quick and patient in providing support and hands-on assistance. In fact, I have never experienced a similar high level of support. He is also happy to listen to suggestions to improve and expand the extension.
Top marks and highly recommended!
