Query: DO NOT BUY THIS REGISTER

Although it seemed to be a good bargain, this register is fatally flawed in that it has no VOID function, no NEGATIVE function or key, and no paper journal; essentially your clerks had better be 100% accurate all the time, as there is NO system for correcting or even finding mistakes after a sale is completed. How the people at Royal could have missed installing such basic functions is beyond me. I can't even ask, as there is also NO CUSTOMER SUPPORT WHATSOEVER.
