Interesting. I have found that the triple-action biners can be pretty "sneaky" when it comes to actually being closed. That is, they will sometimes look like they're closed but, in reality, they will not do the final twist that locks them. I have never had that problem with my snaps. Once the gate hits the crook, that puppy is locked.
Yes it is true that a poorly maintained karabiner is as much use to a climber as an ashtray on a motorbike. Gratefully they are easy to keep working. We buy cans of compressed air from local pc supply shops (they sell them for cleaning keyboards) and blow out the dust that gets trapped inside the "sleeve". A little graphite powder is sometimes useful for keeping the action smooth.
