I had a very bad first impression of Benchmade knives. And a bad second impression. And a lacklustre third impression.
The first Presidio I bought had all manner of problems with the mechanism, especially blade play and several omega-spring failures in the space of a couple months. I got rid of it - even though I really like the design, I couldn't deal with the faulty lock mechanism. :barf:
My second bad impression of Benchmade came with my Alias. The lockbar would slip out of place if you applied pressure to the spine of the blade while in the open position, so I sent it in to Benchmade. Within a week of its return, the problem was worse than before. How many times do they have to repair a knife until they get it fixed?
My third bad impression of Benchmade came with my second Presidio (Why the heck do I keep coming back for more?

). Just like the first one, it had blade play all over the place, an off-centre blade, and the fit and finish really isn't anything to write home about. I got a hell of a deal on this one, so I'm not too broken up that it's a bit shoddy (I've come to expect that from Benchmade), but it still doesn't exactly inspire much confidence in this company...
So, yeah, I've had pretty bad impressions of Benchmade knives all-around, but for some reason, it hasn't stopped me from going back to the company.
