As of 2022 there are many badly performing clones on the market. V2/3GHz NanoVNA uses parts like ADF4350 and AD8342 which are costly and clones have been cutting costs by using salvaged or reject parts.
See official store and look for V2 Plus4/V2 Plus4 Pro versions only to avoid getting a bad clone. We have stopped selling V2.2 versions since October 2020, so all V2 hardware that are not Plus or Plus4 are not made by us and we can not guarantee performance.
Gidday. Today my Nano VNA V2Plus4 arrived. Unfortunately for me our customs department cut into it. Luckily for me the knife has damaged the back of the VNA. Is there a protective case or carry container available? It would be nice to keep everything together. Cheers Paul
I don't know of a bespoke case, but there are many other options discussed in the following thread:
