I do not poo-hoo anything.
Not speaking of someone else, but for automotive useI have personally been in electronics test programs. As such have personally seen in special RFItest chambers how powerful RFI sends ECU outputs down the cliff as if they were commanded by external analog controls.
If the maker of the device has certified his product to be absolutely free of unwanted responses to-, or passing white noise RFI disturbances to other devices I still would maybe consider, but still be very careful in using it. I have not seen such certification, and until I have, will not advise anyone to use it directly (galvanicly) connected to any onboard radio receiver.

It's your decision, but not only your risk, unless you fly alone.
The main rule in my book still is: ''better safe than sorry''

Before poo-pooing the device, try it. I think you will be impressed. Ed Alt, the designer, knows more about spurious RFI getting back to the RX than practically everyone around, on par with Dean Pappas. The man designs electronic systems for the DOD.
As far as safety goes, arming-disarming and fail safe set-up of the CDI via the radio, is much safer than getting to a switch by hand on the plane. Consider what happened to me last year, where the thottle link became disconnected. I simply shut the thing down remotely rather than have to run out a tank or take a chance landing at high idle. Which is more dangerous?
I fly with a group. I don't hesitate using mine. The risk is lower with it in my view than without it. And BTW-I've been flying RC since 1969...I think I know what I'm talking about too
