Defective door hinge on many of these - FAB Defense Vertical Foregrip

I have purchased three of these grips now because they’re the only ergonomically design full size foregrip that I have been able to find in FDE. The design flaw is with the storage compartment door hinges. You open the hinge to put your tools inside the handle and when you try to close it, it is so tight that the hinge breaks off. I am only going to purchase one more of these, and the tools that I have inside will only be used in an utter emergency, which will be the only time that that door will be opened, I just hope it doesn’t break when I try to cause I will be out another $25
