Yes, we offer a warranty on Nurosym for 2 years and on the earpiece electrode for 6 months. Our Nurosym devices are designed to be durable and undergo strict quality tests before being dispatched. If you need to replace your earpiece after the warranty period, you can find them in our extras section. Most issues with using Nurosym stem from electrodes reaching the end of their lifespan rather than problems with the device itself. We also provide ongoing support to all our customers, so feel free to reach out to us if you have any questions.
