The interface is intuitive to use for beginners as well as experts in using bar code software. I have not found anything that I dislike about this program so far. This does exactly what it says it will do with fast response times and ease of use. Having been an employee/customer service rep at Staples many years ago, we used their system for purchasing office supplies. It was slow and cumbersome compared to other systems out there. Optimum Control has really improved my experience by being extremely efficient!
