Abstract:I discuss the status of the soft X-ray transient model. First, I discuss and then compare with observations the assumption that the geometrically thin disc evaporates into an ADAF. Second, I address the problems created by the recent determinations of the distance to SS Cyg, according to which the disc instability model does not apply to this famous dwarf-nova, thus casting doubt on the application of this model to any system at all.
Keywords:Advection dominated accretion flows  Accretion discs  Low-mass X-ray binaries  Dwarf novae  1H 1905+000  SS Cyg
