Opening a Speedstacks Display?

[Pedro]

I have one which stopped working, and would like to take a look inside.
But it has no screws (probably rivets).

Has anyone tryed/managed to open one of those? How?

I've never opened on up completely, but have you tried opening up the battery part and looking for a place that can be unscrewed? There could be something there.

It actually has hidden screws. Try feeling for them around the outside rim ish.

You mean the blue part? Or the black one?
I couldn't find anything so far...
