I must've gotten the bad one that someone else returned already - SB Tactical TF1913 Pistol Stabilizing Brace

Extremely difficult to get the sliding hinge mechanism to release for folding or unfolding, which basically invalidates the entire product by itself, but also in 110+ degree heat the top strut arm starts to bend like a noodle, so if you live in the desert forget about it this thing is worthless to you. Where they got the presence of mind to charge 200 dollars for this flimsy, badly engineered piece of cheap plastic I will never know.
