I am glad to have this filler. At my school we are trying to go paperless. It is expensive. Sometimes hard to maneuver and cumbersome to use. Once I get the hang of it and use it more often I am sure I will become more adept at using the filler.

Excellent support and customer service I registered for an annual membership, but I didn't pay attention that the membership fee is calculated in US dollars.
