Hi, I wish they had a separate rating for version 9 as I would have given it very good. I have been using Nitro for 3 years and have found v9 brilliant. My business has grown and I have needed to buy a new license and thought initially I would upgrade my v9 to v10. A few months ago I purchased v10. However I found some of the functionality that I relied on in v9 not there in v10. I use the software to build pdf documents from a variety of different (converted to pdf) files. There is some file manipulation like optimisation but mostly it is fairly simple work but I find Nitro v9 allows me to really move through this part of my perocess really efficiently. So I had to go back purchase a full priced new copy of v9 (couldn't find any discounted offers and got slammed) for my business and I have not touched my v10 again. Double loss for me and now I am now concerned about the amount of time I might have before v9 goes unsupported. However right now my business is growing and this is what I am focusing on. I don't normally do these type of reviews but I remember very early on one of the owners/senior managers ringing me and gave me good support. For me v10 broke the really good piece of software that v9 was. Hope this helps.
