Inferior to the original ACE Hard Rubber Comb
Disappointing.  Although the Hercules may be a hard rubber comb, the tines are much sharper than the tines of my one remaining ACE Hard Rubber Comb (which are blunt tipped).  The result is that the Hercules comb hurts the scalp when I comb my hair.  The ACE does not.
