Opti Core Pro is advertised with a 180-day money-back guarantee. We recommend confirming the exact current terms directly at checkout before ordering.
A 180-day guarantee window, with a stated return address of PO Box 12730, Ogden, UT 84404.
Whether the 180-day clock starts from the purchase date or the delivery date; what condition returned product must be in; which shipping carrier is required; and who covers return shipping costs. None of that means the guarantee isn't honored as described — it means these specifics aren't confirmed by the pages we could review, so confirm them directly with support.
Contact Opti Core Pro's official customer support directly — not this website — within the guarantee window. Calendar your deadline the day your order arrives.
