I wish I'd heard of them back when I was a student! I just tried it out, and it erased fine *G* Though when not erased, the color isn't as bright as a regular ballpen.
They were epic when writing final drafts of papers (before the advent of 'everything must be typed, omg!') when you didn't want to have to start over on the whole page after you'd written all the way to the last line and made a mistake! b/c it never fails that it's on that last line when you make the error and you're all 'd'oh!'
I haven't figured out one yet, alas! I suspect my teachers would have said the same thing, if they'd known about it back when I was a student though *g*
I used to love erasable ballpens, probably because I couldn't use them, but they had a huge problem: the ink takes a bit more time to dry than usual pens, so if you accidentally put you hand on the still wet text, you'll wipe it all away ;A;

It sounds like you're enjoying them though!
