  We provide a strong evidence for strong monogamy inequality of multi-qubit
entanglement recently proposed in [B. Regula {\em et al.}, Phys. Rev. Lett.
{\bf 113}, 110501 (2014)]. We consider a large class of multi-qubit generalized
W-class states, and analytically show that the strong monogamy inequality of
multi-qubit entanglement is saturated by this class of states.
