This is one of those products with a name that really does say it all: the "Head Spa Massager." And that's probably about the best thing about it.
Just look at this thing. Would you be caught dead wearing one of these? It almost makes the solar fan hat look downright fetching. On the other hand, people might think you're either a cyborg or the victim of a horrible accident, in which case you might get preferential treatment out of fear or sympathy.
Gizmodo quotes the product description thusly: "This patented Italian design incorporates Japanese engineering and utilizes acupressure to relax and soothe your problems away. It's like thousands of tiny fingers simultaneously massaging your scalp."
So it took geniuses from two continents to come up with this piece of work, which goes for $50. And where's it being marketed? On American infomercials, of course. They may be crazy, but they're not stupid.
