Only saw short video on YouTube by a Czech guy had to subtitle in English- it struggled. But what impression I got was valving similar to Huben, but different, 2 safeties, auto load? Not sure what that was. Ballpark 60,000 CZD or about 2,500 U.S. Big number, if accurate, but you know quality is there. Hard value. I’m totally waiting for a detailed video for confirmation. But I’m amped for this one.
