The UV Care Cap is by far the most useless thing i came across in a while.
Get this the ugly plastic cap is changing its color from milky white to purple when the sun shines. In more technical terms it changes to purple when it detects UV radiation. Trust me if the sun shines there is UV, no need for a plastic shield cap to tell you that.
At $9 it makes a great prank gift for your roommate though. You can buy this jewel at Hong Kong's Brando. Brando also has more useful gadgets like the little remote controlled Nintendo figures.
