I've had this for years, its been connected to a pc in the living room that I only use to watch movies on. 
So really it's never been a "regular daily use" keyboard at all and its never really seen much action at all. 
never had any damage or liquids spilt on it.
The box has some alternate keys in it for alt\ctrl\shift that have never been used along with a user manual. 
please email me with any question.
