I like that it allows me to create my own templates, which makes life easier when creating multiple product presentations in bulk; however this does come at some cost (more memory required).
The system has been very helpful with our clients wanting us produce different brochures or sales materials each month/quarter etc - we have had no problems producing what they need! Our client base includes small businesses who require simple leaflets through large organisations requiring complex designs / layouts so both ends of scale are catered too well by their service here :) Highly recommended as you can customise your template easily without having an expensive designer working alongside if needed but also saves time compared against other providers where there would be more hand-holding involved from design stage onwards.
