  Point contact Andreev reflection studies have been conducted on FeSe single
crystals by lowering the temperatures down to 0.5 K. The point contact Andreev
reflection spectra were analyzed in the framework of the two-band model. As a
result, the presence of two anisotropic superconducting gaps in FeSe were
certainly established and their BCS-like temperature dependencies were
obtained. The weights of each gap have been determined and the anisotropy
parameter has been calculated. It is shown, that sub-kelvin temperatures are
necessary to ascertain details of the superconducting gap structure, especially
for multiband materials when Andreev reflection spectroscopy is applied.
