Great product with minor flaw. I initially bought two of these pens. My initial impression was they had great build quality. They have a nice weight, feel very solid, write well and have a sharp stabbing tip. However, the stabbing tips on both pens loosened completely and fell out after about a month. I easily fixed both with JB Weld so they are back in service but this is something that should be addressed with whoever is manufacturing them. Knowing that these are easily fixed if the problem happens again I did not hesitate in buying two more.
