I like that it has a lot of different features to choose from, so you can customize your viewing experience. It also has a great interface for navigating through the software, which is easy to learn. The software itself is very intuitive, and there are lots of helpful tutorials out there online to help with any issues. There isn't anything I dislike about this product. It's easy to use, and it does what we need it to do. We have been using CADI Optimum for almost two years now, and it hasn't given us any problems yet. We used to use an older version of this software before, but it was not as user friendly or intuitive. A significant improvement over our previous solution!
