The extension has all the funtionalities I needed but the date field doesn't work, even on a clean joomla installation.
Bad support. Still have a ticket open for more than 9 months without a reply or solution. Support stopped after the refund period was over!
Some stuff should have been better documented but eventually I found out how stings are to be configured
Value for money
There're better extensions with better support. Once your refund period expires and you can no longer get a refund, the support stops!
