The flux quanta attachment to the electrons creates composite fermions (CFs). The mass, the size and the density of the CF are inconsistent with real material. The sequence of fractional charges which suggest formation of CF agrees with the data but there are no monopoles in GaAs. Hence, the CF model is internally inconsistent. There are two possibilities. (1) The flux quanta are attached to the electrons. This is a theoretical possibility with nothing to do with any experiment ever performed within the last seventy five years. It will violate Maxwell equations and create unreal objects. (2) The CF give a sequence which is deduced from the experimental data and hence agrees with the data itself. In this case the masses of CF, the sizes and the densities are internally inconsistent.
