Merchandising geniuses....
Somehow I'm reminded of a $2.95 el-cheapo 4-banger calculator I bought which had "Solar" printed on its front right under the solar cell, just on the general principle that every man could always use an extra little calculator to play around with.
OK, but when it died a year later, notwithstanding the fact that it was charging under a desk lamp much of the time, I decided to rescue the solar cell inside it just on general principles... that principle being that every man could always use an extra solar cell to play around with.
Four little Phillips-head screws later I made the interesting discovery that the solar cell was merely a cardboard printed picture of a solar cell.
No wonder it didn't stay charged.
