Gets the job done! Amazing, all sorts of adjustments can be made (Text, highlight, signature, templates etc). User friendly and a simple enough design. Cheaper too! My only issue is internet connection, perhaps if it was available offline (I'm not sure if that's a feature or not), it would honestly replace Adobe Acrobat all together.
