I being a novice at computer have been struggling to keep up with my business correspondence from my end....this has been a God-send. I just stumbled on this by accident. Thank you.
Wonderful - the only way to make it better is to make it free or at least cut the cost in half. Thanks so much!! All in all a wonderful service and really worth the price!
Works as you would expect. No flaws, other than I would like to see a way to make the 'circle' option larger for when initials are needed. Great options here.
it's a little bit too expensive for me. I will not have to use it very often, maybe only once or twice a month for work, but i do require the premium package for all of the features that i need to have. so it just seems crazy to me to pay almost $200 a year for something im only going to use 24 times the whole year. other than the too high price, i think its a great program!
Does way better than I expected
Works way better than any other ones I have tried. Will not use anything else. Allows me to make changes to any document I have scanned in so far.
