Well written code.
Easy to install and get up and running.
I have nothing but praise for this software and have even had two subscriptions over the years and used this software to build client sites.
Support is first rate and personal and I really can't see people needing to go elsewhere for this type of extension - this is the best!
The support guys even assisted me in the template design a year or so back through the forum.... kudos!
Incidentally the code is clear and I have made many modifications to the code to suit my customers.
