That's interesting. I suggest that is a placebo effect or something else psychological going on. A gold colored versus a "silver colored" razor of the same model will shave identically. The face doesn't know or care if the razor is gold or silver or some other metal.I have several, and so far the buttons still work on all of them. One thing I have noticed, and it may just be a problem with the one example that I own, but the gold ones seem to be more efficient than my nickel-plated PB.
