We found a genuine discrepancy in NeuroVera's guarantee terms: the guarantee badge included with our product materials states 60 days, while one independent source we found describes a 365-day guarantee instead. We cannot reconcile this difference ourselves.
Confirm the exact current guarantee terms directly on the official checkout page before ordering, and keep a copy or screenshot of what you see at checkout for your own records.
Contact NeuroVera's official customer support directly — not this website — with your order details, within whichever guarantee window you confirmed at your time of purchase.
Calendar your refund deadline the day your order arrives, once you know the actual window that applies to your order.
