It's great! Only problem I had was trying to erase a hi-lited area I accidentally added. The software wanted me to pay for an upgrade for the eraser which I think is ridiculous guys. Other than that, awesome.

Its good for the most part - the downside is it doesnt open for me on the first try and it asks me to sign in everytime i need to print or save a doc. even though I pay for the service. Annoying that it doesnt recognize me when I use the app.

I like that I can bring in any fillable document, it makes everything to do with a business much easier. It's just not very easy to do. I have to remember how to do it every time. Not sure if that is my fualt or if this is just not that user friendly.

EXCELLENT Customer Service
I requested a refund on my annual subscription after it had been taken out of my account. I explained that I don't use the software, and did not need to have my subscription renewed. The person who helped me was very kind, and responded promptly. I had a full refund within 48 hours! EXCELLENT customer service!
