  In a recent Letter Mola et al. \cite{mola} reported magnetization
measurements $M(H,\theta)$ performed on the organic superconductor
$\kappa-$(ET)$_2$Cu(NCS)$_2 (T_c = 9.1$ K) as a function of the magnetic field
$H$ applied at different angles $\theta$ with respect to the $a$-axis
direction. The results \cite{mola} demonstrate:
  (a) the occurrence of pronounced irreversible magnetization $M_{\rm irr}(H)$
jumps and (b) their sudden cessation for $H \ge H_m(T,\theta)$. The boundary
line $H_m(T)$ has been interpreted by Mola et al. as the Q2D vortex lattice
(VL) quantum melting phase transition line \cite{mola}. The purpose of this
comment is to show that the results can be understood in a simple way without
invoking "quantum melting phase transition".
