We stand behind the quality of our hoverboards. You deserve getting a brand new hoverboard that works out of the box, which is why we commit to our guarantee. If you are unhappy with your hoverboard purchase and believe there is an issue with it within 30 days of use, you are covered under our 30 day policy for repairs or replacements. Due to this policy, we highly recommend our customers to first test the hoverboard indoors to make sure it is fully functioning before using it outside. After months of experience, we find this to be the best experience for our buyers, and believe we have one of the fairest and transparent policies on hoverboards today. Please note the following: If the hoverboard is found to be new and defective out of the box, we will replace it for free. You will be responsible for the return shipping back to us. If there are signs of use (any scratches, blemishes, wear on the tires, etc.), we will repair your board. You will be responsible for the return shipping back to us. If there is extensive damage that appears to be incurred by improper usage, negligence, or alterations, we have the right to charge an additional fee to repair the hoverboard. We only accept refunds for brand new hoverboards without signs of use. There is a strict 15% restocking fee for refunds. This fee is not for us to make money, it's simply to cover our shipping costs back and forth as shipping for hoverboards is expensive. We absolutely do not accept refunds for any hoverboards with signs of use.
