We show that "Quantizied Nesting" model misses important features of the magnetic field-induced spin-density-wave (FISDW) phase diagram. Among them are: 1) the FISDW wave vector is not strictly quantized; 2) in some compounds, the FISDW diagram consists of two regions: a) at low temperatures, there are jumps of the wave vector (i.e., the first order transitions between FISDW phases), b) at high temperatures the jumps and the first order transitions disappear but the wave vector is still a non-trivial function of a magnetic field. These are in agreement with the experiments on (TMTSF)2PF6.
