Review on Tenq RS40 Pro Dual Band Standing-Wave Meter & Power Meter - Ultimate SWR Testing and Power Measurement Tool by David Lesperance

There may have only been 2 units sent to me. The first block was broken and rumbled with internal components. The second unit said my 2m radio was off the charts at SWR. I checked everything with a voltmeter, everything is normal. When I clicked on the Diamond SWR power meter, it showed I only got 0.8 on the SWR scale. This calculator didn't work for me at all.
