We analyze the thermodynamical properties of the regular static and spherically symmetric black hole model presented by Mboyne and Kazanas. Equations for the thermodynamical quantities valid for an arbitrary density profile are deduced, and from them we show that the model is thermodynamically unstable. Evidence is also presented pointing to its dynamical instability. The gravitational entropy of this solution based on the Weyl curvature conjecture is calculated, following the recipe given by Rudjord, Gr$arnothing$n and Sigbj$arnothing$rn, and it is shown to have the expected behaviour for a good description of the gravitational entropy.
