I should have read the reviews first
I thought it was a nice idea when I looked at it online.  But you cannot draw smoke through it, only air.  The stem base had to be screwed into untapped wood and did not feel secure.  I didn't read the reviews until I discovered its inherent problems (wish I had) and I don't know if it is worth trying to fix the pipe.  It is too heavy to hold between your teeth (without hands).  I feel ripped off and wish that Amazon had not offered this pipe at all.
