The one I have is great. Not problems as it came from the factory. The only thing that keeps me from carrying it more often is it is a bit heavy. People say it is slow, actually this is the first time that I have heard that, but it is much faster than my kershaw whirlwind. My apparition jumps in my hand when the blade opens. It is wicked fast, and wicked sharp. Oh, the pyramid thumb stud is more slippery and harder to push than the knurled one on my kershaw and I can see where someone may get carried away and push their thumb up onto the opened blade by accident, but I've never done it. I love mine, but it is a bit flashy compared to my minigrip that I carry most. Living as close as I do to NYC, I try to keep a low knife profile. They say that you can remove the spring to make it a nonassist opener, but the spring gives the tension that keeps the blade closed and removing it allows the blade to flop around. You may be able to get the blade to be secure by tightening the screw, but I've heard that it is difficult to hit that happy medium between ease of opening and security of pocket carry. As an assisted opener it is great. Go try one and decide for yourself. Oh, I paid just over $100 for mine at a gun shop in Austin, TX known for their exorbitant prices. Worth every penny. This is the knife that got me hooked on Benchmade.
