You can return Hero for any reason to get a refund within the first 30 days. There is no shipping fee, but you need to return the unit in original packaging. If you decide to return Hero after the 30-day trial, but before the initial 12-month membership period ends, the company automatically charges your credit card for the remaining monthly payments for the first year. You can cancel at any time after the first year, but return the Hero pill dispenser within 30 days of the last month of membership to avoid a $300 charge.
