Had an awful first experience primarily because the app does not give you any option to change your tariff. So I was on the minute-by-minute tariff, and landed up unexpectedly in an out of service area (the service area sucks). I would have had to leave the car for hours being charged minute by minute, so I had to drive to the nearest service area and then catch a bus back to my location. It would have been so much more sensible of I would have been able to change to a day hire tariff.
