Yes there are. If your sensor is rubbish and you call Abbot, they will ask you which meter you are comparing the readings to. If you admit you are comparing to blood readings done by a different meter, they will not give you a new sensor, but will send you test strips for the build in meter.
As if the build in meter would be better than a contour next or Onetouch. In fact the build in meter is rubbish, but Abbot insists that you compare libre readings to readings of the build in blood glucose meter.
However except for this, everything will work the same with or without libre teststrips.
