Hi, Rich,
I thought my post was relevant to the thread .. in that it's hard for newbies to know if we have one of the better/worse nanoVNA's sold on "Amazon" or Aliexpress for instance.
It seems people like me find it difficult to know which buyer to go to, and without knowledgeable feedback like "The device failed xxx test" - on aliexpress everyone posts 5 starts - which helps nobody.
I didn't find the suggestion below "I would strongly advise purchasing for Hugen's site:" before i bought mine ;(
Danke.
