It is very easy to use, fast loading times when using CAD drawings with multiple parts in one drawing file makes it easier than other manufacturers that only support single part files or do not have an option of multi-part design at all! The fact you can share your designs via cloud storage (Dropbox), which I really like as well! There are still some minor bugs here & there but nothing major so far from my experience working daily within this software system since about 5 years now ;) So overall great product especially if used together w/o any errors during development process - best fit into our workflow perfectly due its speed + ease usage while being able create different sprockets sizes / shapes etc without having too much coding involved by yourself :).
