We've been able to use this system for many years now with no issues or problems in our restaurant/bar at all! It allows us (and other staff members) easy access into it as well so we can track everything very easily which has made life much easier than using paper methods of tracking orders etc., I dislike nothing about how simple & user friendly they are - great product!! The ease when adding customers who have yet not booked online but just want their menu items ready upon arrival means less work from myself personally too ;).
