I really like this pen, it's sturdy as hell, my favorite when I'm working or when Im on trekking. I see a lot of people complaining about almost everything, please don't believe them, just try one of this and make your own mind. I had mine for a while, works all the time, it's nice, sturdy, and lightweight, and looks good all the time and you don't need to worry about damage (before someone point the obvious, yes you can always take a hammer an break the pen, Titanium is not impervious to damage, just more corrosion resistance and strong as stainless steel, but lighter, and a little more scratch resistant, so generally speaking, I just say that is more forgiving than most of the aluminum and steel pens available)
So, at the end I'm sure this pen will last, and is more probable that you had the pen lost before you had problems with the quality.
I will totally recommend this pen, it's really a must if you spend a lot of time in saline environments, like sailing at the sea.
