Query: Stopped working . . . what a rip off

These are almost 3 dollars for a dozen of them. After writing with one every day for several months, I found that it stopped working. Theres a built in 'power indicator' kinda thing that reminds me of a thermometer. Well the black colored 'temperature reading' of this thing has been steadily going down for months, is now at 'zero', and this pen won't work at all. What's up with that?! For almost 25 cents per pen, you think they could at least make a quality product that wouldn't stop working.
