great customer service - sam
great, easy to use, saves us a fortune on an extra phone line for a fax. Great customer service, I always use live chat and get answers and resolution within a few minutes. I have only had to use support 3 times in a year because the program is so user friendly.

Fantastic customer service
For some reason I needed this and only once. I got the free trial and then forgot all about it until $115.00 was collected from my account, shock horror. All I can say is you have fantastic customer service, I explained my situation and a refund was issued that same day. Both friendly and speedy. Ace by name and by character, much appreciated. 1 star deducted as I would have liked a reminder email when the free trial was coming to an end.

The UI were strange at times(As I sometimes had to look for something specific) , but overall my experience were really good as I am able to achieve my goal everytime with ease. I were using the edit pdf feature and again a bit of trouble trying to establish what I was looking for, but once I found it, it was quite an ease.
