Thank you for the suggestion Roger. Sesi wasn't on that list of reputable
manufacturers that Dragan mentioned I believe. Is that an issue? This one on
the other hand is? Is it the same connectors collection aside? Nooelec
NanoVNA-H 4 Premium Bundle - Vector Network Analyzer Kit from Authorized
Distributor with 50kHz-1.5GHz https://a.co/d/hJ07u2D

Seesii is a seller of NanoVNA products on Amazon. They probably buy in bulk from Hugen. There are many satisfied customers including some here in this group. The price is reasonable and what you receive in all likelihood will be a genuine -H4. It should come in a brown box with gold lettering and shrink wrapped. If you post a photo of the back and look at the board inside it is easy to tell if it was built by Hugen. If it isn't just send it back to Amazom for a full refund.
