I've had an interaction with @kerwin here on the forum about some inkbird problems and with an offer to try one of the new programmable Inkbird units for "free". He urged me to order one of the units from an Amazon seller and said that I'd be reimbursed through Paypal. I ordered the unit, got it in no time, it seems to be completely new, perfect, all in order, but I've heard nothing from "Kerwin" despite several attempts to communicate. I can't quite imagine an internet scam whereby a purchase from a legitimate seller on Amazon could be exploited, and since I've shared no hackable information and shared any payment information only through a secure Amazon transaction, I don't see how there's any value in an elaborate hoax involving helping me solve my other inkbird problem, but given the nature of the internet, I'm posting a warning. "Kerwin" indeed seems to be legitimately knowledgeable about the inkbird products and there may be some explanation. If the worst outcome is that I have a product that I didn't really need and had no intention of buying, there's not much harm done...especially since the seller has pretty impeccable feedback and it seems likely that I could just get a refund, anyway.
