Uzi Tactical Defender Pen

For effectiveness I give this pen a ten out of ten. It is very durable, it is refillable, has a glass breaker, pocket clip, and can write upside down or underwater. Sadly though it does not come with a DNA catcher crown like the website said it did, since there are actually two differnt models of this pen. But two thumbs up since I will never need to purchase another pen in my life.
