Each umbrella has an unconditional lifetime guarantee (within the U.S. only). If it breaks, just send it back to us for repair or replacement. However, you do need to pay for shipping and the cost of a new beacon chip (we replace the beacon chip for every return). The total cost of return shipping and new beacon chip is USD $24.95. Upon receipt, we will ship you a brand new unit. Due to the high cost of international shipping, this guarantee is valid for U.S. addresses only. Registration of your umbrella is recommended, but not required.
