The 30-day trial begins when you receive your instruments. You will be scheduled for return appointments at UAMS during your trial, at the two-week and four-week intervals. These shorter visits are designed to address any problems you encounter during the adjustment period. At the end of the trial period, you will be able to easily determine hearing aid benefit and if dissatisfied, you may return the instruments, in good condition, for a full refund. Hearing aids at UAMS
