The features are very easy to use with no complex software required once installed in your computer system. I have used this product for many years now without any problem or glitch at all. It has been working perfectly every time i open it up again from my old laptop which had stopped functioning properly some months back (no hard drive). Highly recommended if you need such kind of tool because its affordable too! There's nothing much to dislike about this program as well. This can be considered one of those best tools ever created by man so far when it comes to medical field especially radiology department where images play important role in diagnosis process.
