fool/fuel angel

Evening
So contemplating getting the misfuel Angel device (https://www.misfuellingprevention.co.uk/)
To prevent petrol going into a diesel car.

Are they any good?
Does it cause problems when you're filling up?
Anyone used one.

Your comments/experience please.

Seems a bit pricey.
Suppose the Dragons want their pound of flesh.

Thanks

Why?
It's not rocket science choosing the correct fuel dispenser.
