This reflex hammer is a very simple one - it\'s of the Taylor model, and the production quality is not very good, the head is made of very light, possibly hollow plastic, and it looks a bit unfinished. It is very light, so you may be tempted to use some extra force swinging it. The handle is shaped with the spike on the end for administerinf the plantax reflex test, too, so the basic functionality is there, so for the price you\'ll be getting a functional product, just don\'t expect the quality to be very good.
