Very flexible for creating custom imports & exports to add or modify content en masse or by certain criteria.
Ease of use
Using the premade templates will get you started. Customizing imports requires some work.
Excellent!!! I was unable to install the plugin on my hosted site after working it out on local host. They installed it for me!
Forum, tutorials, examples, built in help.
Value for money
Available support along with power & flexibility provided by extension make it well worth it.
