“My three daughters are at college and I purchased a bullet blocker for each of their back packs. The customer service representatives did an excellent job of tailoring the panels to perfectly fit each of their backpacks. The panels are lightweight, and take up practically no room. One panel was about an inch short and Bullet Blocker replaced it quickly and without any problem at all. I hope not to be a paranoid father, but my daughters are worth the effort, that is why they carry a bullet blocker in their backpack as well as a rubber door stop. It does not hurt to be prepared.” -Andy

“…I received my new custom panel for the Dillon Carry Tote (sooner than I expected). It fit so absolutely perfect it actually looks like part of the bag. Great job & great service. Thank you for your help!” - Joe A.
