Running hot

It isn't a copy.  It is a real Bosch!  It came in A Bosch Box and it says
Bosch right on it.  I don't know where the assumption came from that I was
using a copy.

My only caveat with it is its noise level.  Which makes me wonder whether I
should drop another fifty bucks at some point when cash flow is better,on a
silicone "silencer cradle". I wonder if they really work and whether they
could cause it to overheat, being a relatively new and untested concept.
Anyway, that is enough for tonight.  My mind can only absorb so much
information.
