We've used one for 7 years on a MoFlo.	Performance has been just fine
while running; stable in power and pointing (as HeNes are).  However ours
has failed 3 times with electronic problems inside the head (usually
broken high voltage connections).  Each time the repair was simple and
inexpensive but the downtime is always a nuisance.  My *suspicion* is that
the cylindrical head is too tight for what is crammed in there and there
may be an overheating problem.
