Well it's not mine, but I can say that my Dad's still is. Just checking in, since I've heard it lasts forever.

Mine is. They don't last forever, but the batteries are replaceable.

I pulled the batteries soon after purchase when I read the note on the inner cardboard sleeve:  "The batteries should be periodically replaced to continue functioning properly. The batteries may explode or leak and cause personal injury if disposed in fire, recharged or mixed with other battery types."

I just tried a couple of AA batteries and the LED still works.

Mine didn't have a blinking light, but I didn't buy it in 1995. They must have done a different packaging after the first run.

Yup. Mine is still blinking. I've changed the batteries quite a few times.

Wish I owned this. Such a cool idea.

Same here, the one my brother bought had it and when I bought it around 96 or 97, the packaging was the same but it didn't have the LED light.

Mine still is, I change the battery every few years.

My dads is, but IIRC he did change the batteries once

I bought it the day it was released, but the battery died a couple of years later. I took it out and never replaced it.

Yep. Not sure how many times I've changed the batteries.

How valuable is a copy that still works? I've got this somewhere.

Perhaps vdc530 will start a thread about it?

All of my friends' copies stopped blinking within 12-18 months. My batteries died on the thing sometime in 2000 or 2001. Was the weirdest thing. Never changed the batteries (I'm not sure I ever removed the old batteries either... should probably check to see if they leaked everywhere).

Yes, the members of Pink Floyd (except for Roger Waters, who is a known Soviet agent), after working for several decades in an underground lab in Cambridge, discovered the secret to perpetual energy and cleverly released it to the world in the guise of a CD case. Unfortunately, thanks to Halliburton, Dick Cheney, the real Al Gore, and big energy, the patent was bought, the technology destroyed, and the secret was never used in any useful way. Sad, really.
