Each Miracle Blade World Class order is backed by our 30-Day Money Back Guarantee. In the event you are not completely satisfied with your Miracle Blade, you may return the product for a full refund of the purchase price, minus the shipping and processing costs. The item(s) must be returned regardless if they are opened or not. Before returning the item, you must obtain a Return to Manufacturer Authorization (RMA number) by calling 1-800-793-2186. The RMA number must be visibly written on the outside of the return box so the return can be processed by our returns department. No refunds will be issued for returns without RMA numbers on the outside of the box.
