Only thing that could be better is the head could be smaller. It is about 3/8" OD and nearly 2" long, solid head, limits access to tight places. Milwalkee (sp?) has one that has memory and USB for archiving, but is nearly $400, then they jump to over $2000 for the fiber optic stuff.
I was able to access and see hidden parts of the guts of the transmission last night which was good, but no sign of the missing parts.
