The registries describe this device under different primary UDI-DIs (EUDAMED lists +EPTWTW340450; FDA GUDID lists EPTWTW340450), so their flags are not compared. Device class is stated on each registry's own scale: Class IIb in the EU (EUDAMED), Class II in the US (FDA GUDID). EU and US classes are different schemes, so this is not a disagreement.
