The answer to this question will depend entirely on how well you care for your board. If you avoid leaving the board out in direct sunlight for many hours, rinse it off with fresh water after each use, and ensure that it's completely dry before storing it away, your THURSO SUP should last for many years. Also, keep in mind that every THURSO board is backed by the company's 2-year warranty which covers you in the event of a manufacturing defect.
