Does anyone have any first hand experience of these devices, do they

I know some folks who have used electronic rat repellents that use both
ultrasonic and rf (radio) transmitters. Much to my surprise and some
scepticism they claim they work. I think they said the radio mode was
particularly effective.

As with electronic/electrolytic/magnetic scale inhibitors I suspect the
operative pharse is YMMV: they may work for you, but are not a bulletproof
solution.
