The things I’d want to know:
Does it use latching relays? The Eleccraft T1 does and that means once it has tuned, no power is needed by the tuner to keep the selected coils and caps. If it doesn’t, you’ll need an extra 150mA of supply when out portable.
The demo video shows it matching assorted resistances, XR+0j impedances but doesn’t show reactive loads being matched. Seems a little odd not to show it doing real world matching… i.e. matching for 30m on a 20m dipole.
