Amazon has the glass breaker pen selling at $18.61 with Prime shipping. Not much of a saving on Woot and it will be delivered faster than ordering through Woot.
That being said, I like these pens even if you have to unscrew the pen a little to get the tip to retract all the way.
My wife has the DNA Catcher pen and I have no doubt it will scar the crap out of anyone on the receiving end of the attack.
I keep the Glass Breaker pen in the car to sign deposit slips and help break the windows if I end up at the bottom of a deep lake. Since I live in SoCal we don’t have many deep lakes left so maybe it is currently overkill.
At <$20 these are great pens to keep around for impromptu pen wars or just to pull out and wow some coworkers. I have large hands so writing with the pens isn’t a difficult problem AND they are left-handed compliant too!
