Yes that's the one. Loading the battery now.
Also took the plunge on one of those a few weeks back, when there was a sale, the V3 seems to be based on two MAX2870 synthesizer chips.
Been looking into getting a TinyVNA for quite a few years, but every time I choke on all the different revisions that exist of these handheld VNA's and which to jump on.
Decided to get one of each, one that goes quite low from 10k to 2.7G, and the other goes from 1M to 6G
Both are metal-enclosed-variants with the bigger 4.3" (800x480) IPS screen and 5000Mah/4500Mah battery.
The one with the aluwheel, are quite a bit brighter screenwise.
Looked into what Sysjoint are selling the V3 for in China on their official Taobao channel.. it was significant more, than what you could get them for, on their western optimised salechannels with incl. 25% EUVAT.
