The user interface of this product was pretty good to use for me as an end-user without prior programming experience or training from their support team.
I've been using it since 2014 when i started my job at our organization and had no major issues like any other software that we used before (such as Excel). It's fairly easy to learn how to navigate around once the basics are understood but there were some things which took time to understand fully such as macros etc - otherwise nothing negative so far! We have multiple accounts set up within one single dashboard where all employees can access them easily through various devices including mobiles/tablets. This helped us manage employee schedules more effectively throughout different times zones.
