  The paper by Mayoh and Garcia-Garcia [arXiv:1412.0029v1] is entitled "Can
disorder really enhance superconductivity?". In our opinion, the answer given
by the authors is not satisfactory, and we present the alternative picture. Our
reply to the comment [arXiv:1502.06282] is added in the end, in order to reveal
a series of untrue statements contained in it.
