I like that it is simple yet robust enough so you can customize how your business operates without having too many bells or whistles which are sometimes overkill in other systems! Sometimes there may be some lag time while using certain functions but this isn't something we have run into recently as of now - however if any issues arise do reach out directly via email from support@katanamrpusa.com We use katana mprs primarily because they offer an easy way through our sales process where customers sign up for trial accounts before purchasing more expensive plans/features such as multiple warehouses / sites within one account.
