I've been using it for repairs to lead-free equipment for
a year or more now with no problems.  You *do* need an iron
with a tip temp of around 370 deg C and capable on maintaining 
that temperature while you're making the joint.
In my experience the solder with a small amount, 4% or so, of
silver flows signifcantly better then the plain tin/copper stuff.
