Hello,
I can have used once second hand Vive Pro Eye, but the seller do not have an invoice or proof of purchace for it.
Or maybe he has one and not want to give it, because maybe it was a company purchase.
In case there is a failure during the time covered by the warranty, can I do a RMA for the parts ?
I read that technically the manufacturer have a general idea of when the product was sold, by using the serial number of the product, but maybe HTC is more strict about that ...
