As of 2023 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.
Hi,
Is the Aursinc NanoVNA V2 Plus4 Authentic?

Hi, only the V2 Plus4 version on that listing is genuine, the other versions are clones.
You can also find official stores at:

Thanks
Don't make the mistake I did. Buy it from the official web site. And if you have the extra cash, buy the Plus 4 Pro. The extra bandwidth filters are well worth the money. You never know when you might need them.
I agree 100%
I purchased a Plus 4 Pro a year ago from the Tindie store and have no
regrets.
In my opinion it's worth the extra.

I also agree. I purchased the V2 Plus4 PRO from Tindie and paid for the express shipping. I had it is 3 days! The unit isn't stylish, but it is functional. The aluminum case helps the RF shielding and the added dynmic range and internal 201 points option is most welcomed. Some friends have bought clones from Amazon and regret it, some not. I do wonder if they really know a good vna from a poor one other than working or not working. :-) My old H4 is now in the give-away box. ;-) I suggest you consider paying the extra $100 for the PRO version. Read the advantages on the Tindie website.
