I've been using my P-Touch printer for years and it hasn't yet let me down.  This is my first experience with the black on silver tape.  I like the look, very classy.  These tapes are nice, because they will stay on my children's plastic food storage container through countless cycles in the dishwasher, yet they peel off without leaving not even a hint of residue.  I label everything with these, especially AC adapters.  I never have to wonder which adapter goes with what device.
