Don't worry. We de-duplicate non-anonymous signatures automatically, and anonymous signatures within 24 hours (before personal data is deleted). For anonymous signatories beyond 24 hours, we cannot verify there are no duplicates, though there is one human who manually reads all signatures and will try hard to notice and correct any abuse of the system.
Naturally, we’ll be getting in the Pro to test and will give our opinions on how effective all of this is when we’ve spent a month or two actually using it. But if you’d rather not wait and you’re based outside the US, you can pre-order the Ultrahuman Ring Pro right now, for $479, with shipments beginning in March. If you already have an Ultrahuman Ring, you can also get a trade-in deal to help cut the cost of the new model.
