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.
I have been reading on EEVblog that you have some new products under development which will be available soon. Anything you can tell us about the features/specifications and when they will be available.

I think they are going to introduce a 3D case and battery first, we just got permission from a member of the community to use their 3D printed case design.
V2 Plus will be available in a few weeks and it's a small improvement on sweep speed (200 points/s) and a bit lower noise.
V2 Plus4 (I think that's what it'll be called) is the 4 inch version, I have prototypes of it working well at 400 points/s sweep (highest that the UI plotting code can handle) but another board iteration + production run will take 1-2 months. It will come with a 3D enclosure by default this time.

I've got the H4 in plastic enclosure. I can see it picks up EMI through the case in some extent.
Do you plan a metallic enclosures for your upcoming products? Thanks!
There aren't plans currently (we are all busy with design improvements),
but the 3.2 inch clone you can find on banggood seems to be ok.
