Because we are certain you will be satisfied with your iGrow, we offer a generous money-back guarantee. In order to qualify for this money-back guarantee, you must use the iGrow® 3-4 times per week, as instructed in the owner's manual, for six consecutive months. If in the unlikely event you want to return your iGrow® after this 6-month period, you will have 30 days to request a RMA number to return your iGrow®. Once your product is received, your purchase price (less Shipping and Handling), minus an 18% restocking fee, will be refunded to you. You will also be required to pay for the return shipping cost. Please note that only orders placed directly through Apira Science, Inc. are eligible for the money-back guarantee. You will need to call (561) 465‐7000 to obtain a Return Material Authorization (RMA).
