*snarf*
i just laughed a bit too loud at this thread - great when you work with a bunch (a whisper, a hush, an index ...what is the grouping anyhoo?) of librarians...Ssssssh!
the only problem i have had with my key, in four months, is that it has popped open once or twice - and that it does not fold up all efficiently like an Audi key.
