Review on ATAIRSOFT Counterbalance Balancing Tactical Accessory by Paul Varnado

I bought this to put on a Chinese NIJ 3+ Kevlar helmet. In combination with my sionyx camera and battery, I was able to install the "Anker PowerCore 13000 Portable Charger - Compact 13000mAh 2-Port Ultra-Portable Power Bank Phone Charger with PowerIQ and VoltageBoost Technology" in the battery compartment. I gave this case 4 stars for one simple reason, the screw holes are too short for my helmet. So that's a small disadvantage. I have to punch my own holes but other than that it works as expected
