They were selling a cheap little kit at a store that has a jeweler
screwdriver set with 10 bits, and it included a "penlight" LED
flashlight. Cost $2.99. I needed some of those tiny screwdrivers, so I
bought it. Screwdrivers work fine, but the flashlight is retarded. It
has NO SWITCH. After unscrewing the tip (head with bulb), I found a
piece of paper between the batteries and the bulb. [There are no
instructions]. After removing the paper, it lights up, but there is no
way to turn it off, except to put that paper back, or remove the four
tiny coin cells. Of course it's made in China.... I wonder what idiot
designed that???????????
