Interesting. It looks like they replaced the guts of their old METROVNA DELUXE 250 (up to 250 MHz) with some form of nanoVNA. Case, screen and connectors all look the same. No mention of the nanoVNA on their web pages. There are reviews of the older model posted, including a favorable one in English from the August, 2016 issue of RADCOM.
