Cannot review as there is no trial, just a demo.
Ease of use
From the demo, it appears to be relatively easy to use.
I have tried to contact CRMery numerous times for a basic pre-sales question and have not gotten any response.
Not clear if this will work on a Windows mysql joomla latest install. That was our pre-sales question we can't get answered.
Value for money
This is not an inexpensive Joomla module, but priced well for a CRM system. I wish I could use it!
