The bad news is that it will not work with Joomla 3 and development appears to be stone cold dead. I have delayed moving my site to Joomla 3 for over a year while hoping that someone would update this app. So far, no response - and I can't wait any longer.
Installed very easily. The client had specified some unusual color combinations and procedures. ABPro had the flexibility to handle all of them.
Had one issue with PayPal setup. My post on the support forum was answered immediately and with instructions that were clear and complete.
Had another issued due to the client insisting on strange color combinations. Again, my post on the support forum was answered quickly and with good information.
The client and I are both very pleased with the final result. Support is excellent. Product is flexible and relatively easy to configure.
Well worth the price!
